Abstract

In order to improve performances of the induction motor (IM) speed control under sliding mode (SM) DTC-SVM, the paper proposes a SM DTC-SVM based adaptive load torque. The aim of the suggested approach consists to discard load disturbances effects on the IM operating. For this reason, an adaptive estimator of the load torque has been developed to overcome this drawback. The load torque has been considered as a combination of the following three types: a constant load torque, a linear load torque and a quadratic load torque. Simulation results clearly show that SM DTC-SVM strategy with load estimator offers best performances and load disturbances effects can be completely discarded. Thus, the improvement of the proposed adaptive approach has been observed.
