This book was released on 1994 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical and economic limitations of DC motors have motivated the development of strategies such as vector control for high-performance AC drives. One important element of a vector-control system is the current-regulation loop. Two, PI-based current regulators have been analysed and tested through simulation. Their advantages and shortcomings have been discussed. A long-range predictive current regulator has been designed. Developed from generalized predictive control (GPC), this model-based controller predicts the stator current over several sample intervals. The control output which is used to generate a naturally-sampled PWM waveform is calculated by minimising the sum of the squares of the stator-current errors. The simulation results demonstrate precise steady-state control and, with the regulator model well matched to the system under control, the dynamic performance of the GPC controller is superior to that of the synchronous PI regulator. Modification of a commercial inverter has been described. Details of the gate-drive and protection circuits and PC-interfacing have been given. An asymmetric, regularly-sampled PWM algorithm for PC implementation has been developed. Experimental results have been presented which demonstrate the accurate three-phase waveforms and the smooth transition when the modulation index and/or frequency is changed. A soft-starting algorithm and a slip-compensation control strategy have been implemented on the PC-based induction motor drive. DC and three-phase, AC current measurement have been implemented. Current limiting is used to protect the motor against surge currents during soft starting. The motor is accelerated smoothly to its required speed at which point control is passed to the slip-compensation scheme which ensures that this speed is maintained.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a thorough approach for mastering the behavior and operation of induction motors, an essential device in the modern industrial world. Its way of presentation renders this book suitable for selfteaching by students, engineers, and researchers in the field of electrical engineering. It covers the modern theory of induction motor applications and control methods. The transient analysis of both three-phase and single-phase induction motors as well as that of the double-cage motors are developed. The principles of such modern control methods as Fiel-Oriented Control, Direct Torque Control and Computed Charges Acceleration Method are clearly treated in this monograph. Numerous equations, simulations, and figures are presented.

Book excerpt: "Electric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between maths- and theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo dries, providing readers with the knowledge to select the right technology for a given job." "The third edition includes additional diagrams and worked examples throughout. Now topics include digital interfacing and control of drives, direct torque control of induction motors and current-fed operation in DC drives. The material on brushless servomotors has also been expanded."--BOOK JACKET.

Available in PDF, EPUB and Kindle. Book excerpt: Adjustable Speed Drive (ASD) systems are widely used in industry to effectively improve process efficiency and control. Typically, an ASD system consists of a motor with its speed controlled by a power electronics converter via varying the amplitude and frequency of the input voltage. However, several abnormal insulation failures of random wound motors in ASD applications have been reported. These failures were related to voltage transients caused by inverters employing fast insulated Gate Bipolar Transistors (IGBTs) combined with long cables that connect motors to inverters. This thesis further analyzes the distribution of voltage waveforms generated by a pulse-width modulated (PWM) inverter at the motor terminals and windings. Experimental work was performed at the Motor Systems and Resource Facility (MSRF) at Oregon State University on a specially made 5hp induction motor with taps from the first and second coil and from the first four and last two turns in every phase. Tests were performed with long and short cables and results are compared. A simple simulation model was created in PSpice and used to predict maximum voltage transients across coils and turns. The validation of the model is demonstrated by its capability to predict most of the experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: Written and edited by a team of experts in the field, this exciting new volume presents the cutting-edge techniques, latest trends, and state-of-the-art practical applications in linear and nonlinear system modeling. Mathematical modeling of control systems is, essentially, extracting the essence of practical problems into systematic mathematical language. In system modeling, mathematical expression deals with modeling and its applications. It is characterized that how a modeling competency can be categorized and its activity can contribute to building up these competencies. Mathematical modeling of a practical system is an attractive field of research and an advanced subject with a variety of applications. The main objective of mathematical modeling is to predict the behavior of the system under different operating conditions and to design and implement efficient control strategies to achieve the desired performance. A considerable effort has been directed to the development of models, which must be understandable and easy to analyze. It is a very difficult task to develop mathematical modeling of complicated practical systems considering all its possible high-level non-linearity and cross couple dynamics. Although mathematical modeling of nonlinear systems sounds quite interesting, it is difficult to formulate the general solution to analyze and synthesize nonlinear dynamical systems. Most of the natural processes are nonlinear, having very high computational complexity of several numerical issues. It is impossible to create any general solution or individual procedure to develop exact modeling of a non-linear system, which is often improper and too complex for engineering practices. Therefore, some series of approximation procedures are used, in order to get some necessary knowledge about the nonlinear system dynamics. There are several complicated mathematical approaches for solving these types of problems, such as functional analysis, differential geometry or the theory of nonlinear differential equations.
