Switched Reluctance Motor Drives

Switched Pdf [Pdf/ePub] eBook

Switched Reluctance Motor Drives by R. Krishnan Book Summary:

The switched reluctance machine (SRM) is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. Because they require a power electronic converter and controller to function, however, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine. Switched Reluctance Motor Drives provides that understanding. It presents a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low- and high-performance controllers. The book includes an in-depth study of acoustic noise and its minimization along with application examples that include comparisons between ac and dc drives and SRM drive. The result is the first book that provides a state-of-the-art knowledge of SRMs, power converters, and their use with both sensor-based and sensorless controllers. Switched Reluctance Motor Drives enables both students and engineers to learn all aspects of SRM drive systems and appreciate the interdependence of the various subsystems in performance optimization.

Switched Linear Systems

Switched Pdf [Pdf/ePub] eBook

Switched Linear Systems by Zhendong Sun Book Summary:

Switched linear systems have enjoyed a particular growth in interest since the 1990s. The large amount of data and ideas thus generated have, until now, lacked a co-ordinating framework to focus them effectively on some of the fundamental issues such as the problems of robust stabilizing switching design, feedback stabilization and optimal switching. This deficiency is resolved by this book which features: nucleus of constructive design approaches based on canonical decomposition and forming a sound basis for the systematic treatment of secondary results; theoretical exploration and logical association of several independent but pivotal concerns in control design as they pertain to switched linear systems: controllability and observability, feedback stabilization, optimization and periodic switching; a reliable foundation for further theoretical research as well as design guidance for real life engineering applications through the integration of novel ideas, fresh insights and rigorous results.

Stability Theory of Switched Dynamical Systems

Switched Pdf [Pdf/ePub] eBook

Stability Theory of Switched Dynamical Systems by Zhendong Sun,Shuzhi Sam Ge Book Summary:

There are plenty of challenging and interesting problems open for investigation in the field of switched systems. Stability issues help to generate many complex nonlinear dynamic behaviors within switched systems. The authors present a thorough investigation of stability effects on three broad classes of switching mechanism: arbitrary switching where stability represents robustness to unpredictable and undesirable perturbation, constrained switching, including random (within a known stochastic distribution), dwell-time (with a known minimum duration for each subsystem) and autonomously-generated (with a pre-assigned mechanism) switching; and designed switching in which a measurable and freely-assigned switching mechanism contributes to stability by acting as a control input. For each of these classes this book propounds: detailed stability analysis and/or design, related robustness and performance issues, connections to other control problems and many motivating and illustrative examples.

Stabilization of Switched Nonlinear Systems with Unstable Modes

Switched Pdf [Pdf/ePub] eBook

Stabilization of Switched Nonlinear Systems with Unstable Modes by Hao Yang,Bin Jiang,Vincent Cocquempot Book Summary:

This book provides its reader with a good understanding of the stabilization of switched nonlinear systems (SNS), systems that are of practical use in diverse situations: design of fault-tolerant systems in space- and aircraft; traffic control; and heat propagation control of semiconductor power chips. The practical background is emphasized throughout the book; interesting practical examples frequently illustrate the theoretical results with aircraft and spacecraft given particular prominence. Stabilization of Switched Nonlinear Systems with Unstable Modes treats several different subclasses of SNS according to the characteristics of the individual system (time-varying and distributed parameters, for example), the state composition of individual modes and the degree and distribution of instability in its various modes. Achievement and maintenance of stability across the system as a whole is bolstered by trading off between individual modes which may be either stable or unstable or by exploiting areas of partial stability within all the unstable modes. The book can be used as a reference for academic research on switched systems or used by graduate students of control theory and engineering. Readers should have studied linear and nonlinear system theory and have some knowledge of switched and hybrid systems to get the most from this monograph.

Switched Time-Delay Systems

Switched Pdf [Pdf/ePub] eBook

Switched Time-Delay Systems by Magdi S. Mahmoud Book Summary:

In many practical applications we deal with a wide class of dynamical systems that are comprised of a family of continuous-time or discrete-time subsystems and a rule orchestrating the switching between the subsystems. This class of systems is frequently called switched system. Switched linear systems provide a framework that bridges the linear systems and the complex and/or uncertain systems. The mo- vation for investigating this class of systems is twofold: ?rst, it has an inherent multi-modal behavior in the sense that several dynamical subsystems are required to describe their behavior, which might depend on various environmental factors. Second, the methods of intelligent control systems are based on the idea of swit- ing between different controllers. Looked at in this light, switched systems provide an integral framework to deal with complex system behaviors such as chaos and multiple limit cycles and gain more insights into powerful tools such as intelligent control, adaptive control, and robust control. Switched systems have been inves- gated for a long time in the control and systems literature and have increasingly attracted more attention for the past three decades. The number of journal articles, books, and conference papers have grown exponentially and a number of fundam- tal concepts and powerful tools have been developed. It has been pointed out that switched systems have been studied from various viewpoints.

Optimal Control of Switched Systems with Application to Networked Embedded Control Systems

Switched Pdf [Pdf/ePub] eBook

Optimal Control of Switched Systems with Application to Networked Embedded Control Systems by Daniel Görges Book Summary:

This thesis addresses optimal control of discrete-time switched linear systems with application to networked embedded control systems (NECSs). Part I focuses on optimal control and scheduling of discrete-time switched linear systems. The objective is to simultaneously design a control law and a switching (scheduling) law such that a cost function is minimized. This optimization problem exhibits exponential complexity. Taming the complexity is a major challenge. Two novel methods are presented to approach this optimization problem: Receding-horizon control and scheduling relies on the receding horizon principle. The optimization problem is solved based on relaxed dynamic programming, allowing to reduce complexity by relaxing optimality within predefined bounds. The solution can be expressed as a piecewise linear (PWL) state feedback control law. Stability is addressed via an a priori stability condition based on a terminal weighting matrix and several a posteriori stability criteria based on constructing piecewise quadratic Lyapunov functions and on utilizing the cost function as a candidate Lyapunov function. Moreover, a region-reachability criterion is derived. Periodic control and scheduling relies on periodic control theory. Both offline and online scheduling are studied. The optimization problem is solved based on periodic control and exhaustive search. The online scheduling solution can again be expressed as a PWL state feedback control law. Stability is guaranteed inherently. Several methods are proposed to reduce the online complexity based on relaxation and heuristics. Part II focuses on optimal control and scheduling of NECSs. The NECS is modeled as a block-diagonal discrete-time switched linear system. Various control and scheduling codesign strategies are derived based on the methods from Part I regarding the structural properties of NECSs. The methods presented in Part I and II are finally evaluated in a case study.

Switched-capacitor DACs Using Open Loop Output Drivers and Digital Predistortion

Switched Pdf [Pdf/ePub] eBook

Switched-capacitor DACs Using Open Loop Output Drivers and Digital Predistortion by N.A Book Summary:

High-speed communication systems, such as the 10 Gb/s Ethernet standard for copper cabling (10GBASE-T), use digital signal processing (DSP) to overcome the noise and bandwidth constraints of communication channels and, thereby, improve network throughput. The sophistication of these DSP techniques is possible because engineers can implement them using very little area and power in modern CMOS processes. And as CMOS technology scales, the power and area costs of digital logic become even more favorable. The requirements of communication systems also put pressure on circuit designers to develop higher-fidelity, higher-speed digital-to-analog converters (DACs). Unfortunately in this case, CMOS technology scaling offers a mixed bag of trends: some favorable to the most prevalent techniques used in DAC design and others unfavorable. The research presented in this dissertation is an attempt to let CMOS scaling trends guide the DAC design process. To this end, we have developed a new DAC architecture that relies on DSP to overcome some of the limitations encountered in analog and mixed signal design. The architecture consists of a digital predistortion block, a switched-capacitor DAC core, an open-loop output driver, a calibration ADC and a calibration algorithm. During normal operation, the predistortion block operates on the input data stream in such a way that nonlinearties in the DAC core and open-loop output driver are cancelled. Because these nonlinearities can change over time, the calibration ADC monitors the DAC output in the background, allowing the calibration algorithm to continuously update the predistortion coefficients. The predistortion block is implemented as a lookup table that re-maps each input sample to a unique internal value. This allows the predistorter to consume low power, but it also limits the kinds of errors that can be cancelled. Only memoryless nonlinearities, which are nonlinearities that are not a function of signal frequency, can be corrected. Existing DAC architectures are not good candidates for this kind of correction because their performance varies significantly across frequency. Therefore, the architecture that we have developed was designed so that its dominant nonlinearity mechanisms are approximately memoryless relative to the frequencies of interest. A 12-bit, 800-MS/s prototype chip demonstrating the new architecture was fabricated in a 90-nm CMOS process. The prototype achieves better than 58 dB SFDR for signal frequencies below 200 MHz and better than 53 dB SFDR for signal frequencies below 400 MHz. The full-scale output current is 16 mA, but by changing the resistive load seen by the DAC, we tested output voltage swings from 0.65 Vppd to 2.9 Vppd. We could discern no difference in SFDR performance for large or small output voltage swings.

Dynamics and Control of Switched Electronic Systems

Switched Pdf [Pdf/ePub] eBook

Dynamics and Control of Switched Electronic Systems by Francesco Vasca,Luigi Iannelli Book Summary:

The increased efficiency and quality constraints imposed on electrical energy systems have inspired a renewed research interest in the study of formal approaches to the analysis and control of power electronics converters. Switched systems represent a useful framework for modeling these converters and the peculiarities of their operating conditions and control goals justify the specific classification of “switched electronic systems”. Indeed, idealized switched models of power converters introduce problems not commonly encountered when analyzing generic switched models or non-switched electrical networks. In that sense the analysis of switched electronic systems represents a source for new ideas and benchmarks for switched and hybrid systems generally. Dynamics and Control of Switched Electronic Systems draws on the expertise of an international group of expert contributors to give an overview of recent advances in the modeling, simulation and control of switched electronic systems. The reader is provided with a well-organized source of references and a mathematically-based report of the state of the art in analysis and design techniques for switched power converters. Intuitive language, realistic illustrative examples and numerical simulations help the reader to come to grips with the rigorous presentation of many promising directions of research such as: converter topologies and modulation techniques; continuous-time, discrete-time and hybrid models; modern control strategies for power converters; and challenges in numerical simulation. The guidance and information imparted in this text will be appreciated by engineers, and applied mathematicians working on system and circuit theory, control systems development, and electronic and energy conversion systems design.

Optical Burst Switched Networks

Switched Pdf [Pdf/ePub] eBook

Optical Burst Switched Networks by Jason P. Jue,Vinod M. Vokkarane Book Summary:

Next-generation high-speed Internet backbone networks will be required to support a broad range of emerging applications which may not only require significant bandwidth, but may also have strict quality of service (QoS) requirements. Furthermore, the traffic from such applications are expected to be highly bursty in nature. For such traffic, the allocation of static fixed-bandwidth circuits may lead to the over-provisioning of bandwidth resources in order to meet QoS requirements. Optical burst switching (OBS) is a promising new technique which attempts to address the problem of efficiently allocating resources for bursty traffic. In OBS, incoming data is assembled into bursts at the edges of the network, and when the burst is ready to be sent, resources in the network are reserved only for the duration of the burst. The reservation of resources is typically made by an out-of-band one-way control message which precedes the burst by some offset time. By reserving resources only for the duration of the burst, a greater degree of utilization may be achieved in the network. This book provides an overview of optical burst switching. Design and research issues involved in the development of OBS networks are discussed, and approaches to providing QoS in OBS networks are presented. Topics include: - Optical burst switching node and network architectures - Burst assembly - Signaling protocols - Contention resolution - Burst scheduling - Quality of service in OBS networks

The first two parts of this book present tutorial lectures by leading researchers in the area introducing the reader to recent achievements on switching and control and on Gaussian processes. The third part is devoted to the presentation of original research contributions in the area; among the topics addressed are car control, bounding algorithms, networked control systems, the theory of linear systems, Bayesian modeling, and surveying multiagent systems.

Saturated Switching Systems

Switched Pdf [Pdf/ePub] eBook

Saturated Switching Systems by Abdellah Benzaouia Book Summary:

Saturated Switching Systems treats the problem of actuator saturation, inherent in all dynamical systems by using two approaches: positive invariance in which the controller is designed to work within a region of non-saturating linear behaviour; and saturation technique which allows saturation but guarantees asymptotic stability. The results obtained are extended from the linear systems in which they were first developed to switching systems with uncertainties, 2D switching systems, switching systems with Markovian jumping and switching systems of the Takagi-Sugeno type. The text represents a thoroughly referenced distillation of results obtained in this field during the last decade. The selected tool for analysis and design of stabilizing controllers is based on multiple Lyapunov functions and linear matrix inequalities. All the results are illustrated with numerical examples and figures many of them being modelled using MATLAB®. Saturated Switching Systems will be of interest to academic researchers in control systems and to professionals working in any of the many fields where systems are affected by saturation including: chemical and pharmaceutical batch processing, manufacturing (for example in steel rolling), air-traffic control, and the automotive and aerospace industries.

This book examines switched systems from a control-theoretic perspective, focusing on stability analysis and control synthesis of systems that combine continuous dynamics with switching events. It includes a vast bibliography and a section of technical and historical notes.

Switched on Pop

Switched Pdf [Pdf/ePub] eBook

Switched on Pop by Nate Sloan,Charlie Harding Book Summary:

Pop music surrounds us - in our cars, over supermarket speakers, even when we are laid out at the dentist - but how often do we really hear what's playing? Switched on Pop is the book based on the eponymous podcast that has been hailed by NPR, Rolling Stone, The Guardian, and Entertainment Weekly for its witty and accessible analysis of Top 40 hits. Through close studies of sixteen modern classics, musicologist Nate Sloan and songwriter Charlie Harding shift pop from the background to the foreground, illuminating the essential musical concepts behind two decades of chart-topping songs. In 1939, Aaron Copland published What to Listen for in Music, the bestseller that made classical music approachable for generations of listeners. Eighty years later, Nate and Charlie update Copland's idea for a new audience and repertoire: 21st century pop, from Britney to Beyoncé, Outkast to Kendrick Lamar. Despite the importance of pop music in contemporary culture, most discourse only revolves around lyrics and celebrity. Switched on Pop gives readers the tools they need to interpret our modern soundtrack. Each chapter investigates a different song and artist, revealing musical insights such as how a single melodic motif follows Taylor Swift through every genre that she samples, André 3000 uses metric manipulation to get listeners to "shake it like a Polaroid picture," or Luis Fonsi and Daddy Yankee create harmonic ambiguity in "Despacito" that mirrors the patterns of global migration. Replete with engaging discussions and eye-catching illustrations, Switched on Pop brings to life the musical qualities that catapult songs into the pop pantheon. Readers will find themselves listening to familiar tracks in new waysand not just those from the Top 40. The timeless concepts that Nate and Charlie define can be applied to any musical style. From fanatics to skeptics, teenagers to octogenarians, non-musicians to professional composers, every music lover will discover something ear-opening in Switched on Pop.

TheSwitching Function

Switched Pdf [Pdf/ePub] eBook

TheSwitching Function by C.C. Marouchos Book Summary:

This book demonstrates the usefulness of the switching function in analyzing powers electronic circuits in the steady state. A procedure is suggested for the effective application of this effective application of this method for the analysis of all types of power electronic circuits. The Kirchoff's Laws and the Superposition theorem are applied by introducing the appropriate switching functions in order to derive Unified Expressions of voltage and current in switched circuits valid at all times. The exact expressions of the current in each semiconductor device in the circuit enables the circuit designer to collect all the relevant data to set the ratings of the device such as rms, average and peak values of voltage and current. The order of the voltage and current harmonics at any point in the circuit are derived with simple arithmetic. Compact expressions are derived for Sinusoidal PWM signals based on the switching function. The order, magnitude and phase of each component are derived directly from the expression with simple arithmetic. The educator has a simple way to present to his students the mechanism of operation of complex switched circuits where all the statements regarding their operation are actually presented in the model of the circuit.

Switched On

Switched Pdf [Pdf/ePub] eBook

Switched On by John Elder Robison Book Summary:

‘For the first time in my life, I learned what it was like to truly "know" other people's feelings. It was as if I'd been experiencing the world in black and white all my life, and suddenly I could see everything — and particularly other people — in brilliant beautiful colour.’ People with autism have trouble reading the unspoken signals of others. The conventional wisdom says they don't have the wiring in their brains to do it. But now, thanks to astounding advances in brain-mapping technologies, a revolutionary new brain therapy called Transcranial Magnetic Stimulation (TMS) is being pioneered at Harvard Medical School. In Switched On, we follow New York Times bestselling author and ‘free-range Aspergian’ John Elder Robison as he journeys towards having his emotional intelligence ’unlocked‘ by this remarkable new treatment. Led by Harvard professor Dr Pascual-Leone, TMS uses an electromagnetic field to induce signals in the outer layer of the brain, to help autistic people develop the ability to read other people's unspoken emotional cues. Astonishingly, TMS represents a new frontier of scientific possibility for people with autism spectrum disorders, as well as those living with depression, bi-polar disorder, and other conditions. John Robison’s story of how he came to awaken the dormant pathways inside his mind is remarkably compelling and entirely unique, but this is also a book about the remarkable advances in the way we view, and treat, a variety of psychological conditions. Switched On is a real-life Flowers for Algernon with a happy ending — a compelling memoir that blends Robison’s brilliant storytelling and humour with cutting-edge neuroscience, electronics, and a little bit of rock and roll. PRAISE FOR JOHN ELDER ROBINSON ‘Writing with a simple eloquence that is, by turns, poignant and comic, Robison deftly weaves neuroscience into a compelling narrative.’ The Sydney Morning Herald ‘Robison’s approachable account is not only crystal clear, but exciting and full of promise.’ The Listener
