摘要：

The large torque ripples exist in induction motors based on conventional direct torque control (DTC) system, especially at a low speed. For the problem of DTC, fuzzy control theory is applied to DTC system. Based on fuzzy control of induction motor direct torque control system model is constructed in this paper. Fuzzy controller in the system selects the voltage space vector. The control system is simulated on the platform of Matlab/simulink. The results of the simulation prove that the method of the fuzzy DTC controller can effectively improve the low-speed performance of the induction motor, reduce the torque ripple, and have a good dynamic response performance.
