The torque response of direct torque control (DTC) was faster than that of vector control. But conventional DTC had the disadvantages of torque ripple, flux ripple and large harmonic current, which may lead to higher copper loss of stator and lower driving efficiency. Based on the basic principle of DTC, a new control strategy, which used flux chain and torque fuzzy controller instead of traditional hysteresis comparator, was proposed to solve this problem. The conventional fuzzy controller may have insufficient fuzzy rules or insufficient application, which led to the deterioration of fuzzy control effect. The torque loop was added to the variable domain fuzzy control. The fuzzy DTC system was simulated by MATLAB/Simulink. The simulation results showed that the fuzzy control system could effectively suppress torque ripple, flux ripple and harmonic current.
