Abstract :
A flux level deadbeat control of direct field oriented high-power induction servo motor drives using an adaptive rotor flux observer is presented. In this system, an adaptive rotor flux observer of a full-order type is used not only to construct the direct field oriented controller but also to identify the stator and rotor resistances of the servo motor. The rotor flux observer is used to reduce the sensitivity of a deadbeat controller to parameter sensitivity. The fundamental characteristics of this system are discussed on the basis of experimental and simulation results. The induction servo motor drive system employing this method is used to improve the efficiency of an induction servo motor without sacrificing dynamic performance
