Abstract
To solve the problem of larage torque and flux linkage ripples in traditional model predictive torque control (MPTC) for permanent magnet synchronous motor (PMSM),an improved duty cycle MPTC method was proposed which selected voltage and duty cycle simultaneously.In this method,each voltage vector's duty cycle was calculated which made errors of torque and flux linkage minimum at the next sampling instant,and then the optimal combination of the voltage vector and its duty cycle would be selected by a cost function,and torque and flux linkage were considered simultaneously in the process of calculating duty cycle.Experimental results show that the proposed method can effectively reduce torque and flux linkage ripples.关键词
