Abstract

In order to get better performance at different speed regions in Direct Torque Control (DTC) for induction motor system, a speed adaptive strategy combining two control models are established-hexagon flux linkage control model and SVM-DTC control model. The new method takes full advantage of two models and makes a transition between them according to rotor speed. According to the result analysis and comparative study, the proposed scheme is feasible and correct by combination and smooth transition of two control models.
