基于模糊滑模控制的毂电机转矩控制响应研究

Simulation Research of Torque Control Response of Electric Vehicle Hub Motor Based on Fuzzy Sliding Mode Control

轮毂电机电动汽车通过调节车轮转矩实现对汽车的稳定性控制。电机转矩控制方式主要有电流矢量控制和直接转矩控制,但控制过程中跟踪精度较低且转矩冲击大。为提升轮毂电机转矩跟踪精度、减小转矩冲击,基于模糊滑模控制方法对电流矢量控制进行改进,并通过MATLAB/Simulink进行建模与仿真,改进后的电流矢量控制方法得到了有效的验证。

Wheel electric vehicles can achieve the control stability of the vehicle by adjusting the torque of the wheel.The motor torque control methods mainly include current vector control and direct torque control,but the two methods have disadvantages of low tracking accuracy and large torque shock during the process of control.In order to improve the torque tracking accuracy of the hub motor and reduce the torque shock,this paper improves the current vector control based on the fuzzy sliding mode control method ,and simulates the new control method by MATLAB/Simulink,which verifies the effectiveness of the improved current vector control method.
