摘　　要：在汽车换挡过程中,电机控制需要从力矩环切换到速度环,进行速度跟踪。若速度跟踪准确,则从速度环切换到力矩环对电机控制,而在此过程中电流调节器存在饱和问题。针对上述问题,利用一种有效的方法来解决换挡过程中电流调节器的饱和问题。该方法通过电流解耦环和电压补偿环的控制,能够解决永磁同步电机在速度变化较大时电流调节器饱和的问题,并且能够快速、准确地跟踪电流。最后建立了电流解耦和电压补偿的PMSM的双闭环控制系统模型,仿真结果证明了该方法的可行性,并且在工程实际中得到了验证。During the process of the shift gears in the car, the motor control needs from the torque loop switch to the speed loop, and track the speed of the motor. If the tracking of the speed is very accurate, the motor control needs from the speed loop switch to torque loop, and in this process the current regulator exists the saturation problem. In allusion to the above problem, an efficient method was proposed to solve the saturation problem of current regulator. This method can solve the saturation problem of current regulator when the speed of PMSM change largely by control the decoupling current controller and the voltage command compensator, and can track the current lastly and accurately. Then the two closed loops control system was established with the decoupling current controller and the voltage command compensator. The simulation results prove the feasibility of this method, which is verified by engineering practice.
