Vector control has become a powerful and frequently adopted technique that permits the use of induction and synchronous machine drives for high-performance applications previously restricted to unwieldy d.c. drives. This book provides detailed discussion of the various forms of vector control of smooth-air-gap and salient-pole electrical machines supplied by impressed stator voltages, currents, or impressed rotary currents. It includes coverage of rotor oriented, rotor-flux oriented, stator-flux oriented, and magnetizing-flux oriented control. Other topics include the necessary decoupling circuits, the effects of non-ideal drives, and rotor speed and rotor resistance identification by means of model reference adaptive control theory. This is an ideal text for students and for anyone requiring in-depth coverage of space phasor and generalized electrical machine theories and the control of variable-speed a.c. drives. - from Amzon
