Abstract
In this paper, a novel field weakening scheme for the induction machine by the voltage control strategy is presented. The proposed algorithm ensures producing the maximum torque over the entire field weakening legion. Also by introducing the direct field-oriented control in the field weakening legion with large variation in machine parameters, the drive system can obtain the robustness to machine parameter variation. Moreover, by using estimated speed, sensorless speed control can be possible in very high speed lesion. Experimental results for a laboratory induction motor drive system confirm the validity or the proposed control algorithm.
