Abstract: In order to effectively solve the problems of poor performance, low accuracy, and long time in power smoothing control of automotive drive motors, a torque prediction based power smoothing control method for automotive drive motors is proposed. Analyse the working principle and performance of automotive drive motors, establish motion equations for automotive drive motors, and predict the torque of the drive motors. Calculate the power smoothing coefficient of the car drive motor, and use the corresponding speed error and speed error derivative as inputs to design a fuzzy self disturbance suppression controller for torque control. Establish a power smooth control model for the automotive drive motor by setting the active power command output by the inverter level through the controller. The experimental results show that the power of the car drive motor controlled by this method is smoother, the control accuracy is higher, and the control time is shorter.

Keywords: torque prediction; drive motor; power smoothing control; fuzzy ADRC controller.
