摘要
Abstract
The problem of large torque ripples exists in conventional direct torque control (DTC). Based on the consideration of the six-phase induction motor with its own characteristics and analysis of the mathematical model, the paper proposed a six-phase induction motor direct torque control method. Firstly, the mathematical model of motors with normal and stator winding open-circuited conditions was built and analyzed respectively. Furthermore, formulation of a space vector pulse width modulation (SVPWM) provides a method to reduce stator current harmonics of the motor. Analysis of torque and flux provides a theoretical basis for the direct torque control. Finally, using the fuzzy reasoning and changing the duty ratio of the vector action time method, the inverter can output any angle and amplitude of the voltage vector. Experimental results show that the proposed strategy is able to reduce torque ripples and can improve current waveforms, and the torque dynamic response of the system is fast.关键词
