摘　　要：为了减小助力电动机的转矩波动,实现助力电动机电流的准确跟踪,提出了基于二维模糊控制器的相位超前补偿及模糊自适应PID控制策略.仿真结果表明,该方法减小了系统超调量,响应时间缩短,输出响应平稳,具有很好的动态跟踪性能和稳态精度,有效提高了系统的抗干扰能力和鲁棒性.In order to achieve the exact tracking of the motor current,decrease the torque＇s wave motion of the direct motor,the control strategy of the two-dimensional fuzzy controller of phase-lead compensation and fuzzy self-adaptive PID control were proposed. The simulation results showed that the controller reduced the overshoot and shorted the response time. With stable output response and good dynamic performance and steady-state precision,it improved the system of anti-interference ability and robustness.
