摘　　要：针对传统电动汽车用永磁同步电机直接转矩控制系统中存在的转矩和磁链脉动较大的问题,将模型预测转矩控制应用于电动汽车控制中,并在单矢量模型预测转矩控制的基础上提出了一种双矢量转矩无差拍模型预测转矩控制策略,减小了控制系统转矩和磁链的脉动,并提升了系统的动、稳态性能,通过Matlab/Simulink仿真和DSP综合实验开发平台实验验证了所改进的基于转矩无差拍原理的双矢量MPTC控制算法的正确性和可行性。Aiming at the problem of large torque and flux ripple in the direct torque control system of permanent magnet synchronous motor for electric vehicles,this paper applies model predictive torque control to electric vehicle control.On the basis of single vector model predictive torque control,a two-vector deadbeat model predictive torque control strategy is proposed,which reduces the torque and flux ripple of the control system.It also improves the dynamic and steady-state performance of the system.The correctness and feasibility of the improved two-vector MPTC control algorithm based on the deadbeat principle of torque are verified by the simulation of MATLAB/Simulink and the experiment of the integrated experimental development platform of DSP.
