Abstract：On the basis of torque following topology,the general dual-motor torque synchronous control system is analyzed.In traditional algorithms,the torque error is controlled in the open loop.Factors which have effects on synchronous error ratio are analyzed by formula derivation.Then a novel torque synchronous control finite control set model predictive control(FCS-MPC) algorithm based on the unified predictive model for dual-motor system is proposed.The q-axis current synchronous error between two motors is taken as a state variable and closed-loop controlled in the predictive point of view.In this way,the synchronous error is allowed to participate in switching state selection.The experimental results show that the proposed algorithm can achieve torque synchronous control.
