This book describes intelligent control and its use in power electronic systems, specifically AC motor drives and uninterruptable power supply (UPS) systems. The book covers both the fundamentals of the subject and its practical applications. From the Foreword by Lofti A. Zadeh, Director of Berkeley Soft Computing Center, California: qWhat is unusual about [this book] is that it starts with a description of more or less classical control techniques; moves on to modern control and state space techniques; addresses in detail the complex issues arising in the analysis and design of robust control; takes up digital signal processing controllers; and finally, presents a very insightful exposition of soft computing techniques and their application to advanced control of AC drives and UPS systems.qUsually a snubber circuit is required across each switch containing at least an R-C combination in series and a diode ... 3.4 UPS inverters Either of the circuits, Fig. 3.4 or Fig. 3.5, may be used for a single-phase UPS. However, Fig. 3.4 is preferable at low power because the center-tapped transformer is somewhat larger than a transformer without a ... Block diagram of equivalent control for speed control.
