Abstract
There are still large torque and flux ripples in duty cycle model predictive torque control(MPTC) because the second voltage can only be zero vector.At the same time,the cost function contains torque and flux,in which the weighting factors need to be designed.But the design of the weighting factors is difficult.To solve the above problems,MPTC based on two-vector without weighting factors was proposed.In this method,the second vector was from zero vector to non-zero vector and weighting factors were not designed in the cost function.Experimental results show that the proposed method and the duty cycle MPTC have the same fast dynamic performance.Furthermore,torque and flux ripples are reduced under the proposed method and the steady-state performance of the system is also improved.关键词
