Abstract

For the model predictive torque control (MPTC) strategy, the limited quantity of optional voltage vectors leads to large torque and flux ripples, while the weighting factor needs to be designed. Therefore, a dual torque duty cycle MPTC based on the extended voltage vector is proposed in this paper. First, a dual torque duty cycle MPTC that eliminates the weighting factor is implemented after analyzing the impact of various weighting factors on control performance. The stator flux and electromagnetic torque are converted into the equivalent active torque and reactive torque by the instantaneous power theory, and the cost function is redesigned. On this basis, a duty cycle MPTC based on the extended voltage vector is studied, which expands the set of candidate voltage vectors and optimizes the candidate voltage vectors selection, to enhance the steadystate performance while reducing computational complexity. Experiments verify that this method has small torque and flux ripples, no weighting factor and low complexity.
