摘　　要：纯电动汽车作为绿色交通工具,正在走进我们的生活。电动汽车的调速系统控制是电动汽车的关键技术之一,文章在直流电机的双闭环调速系统中加入模糊PID的控制策略,在Matlab/Simulink中建立整车模型,将控制策略在汽车的起动、加速、匀速、制动等工况中仿真,结果显示该控制策略对电机的调速系统具有良好稳定的动态和静态特性,各工况下的车速偏差不超过0.5 km/h,达到目标车速的时间最大缩短了20%,转矩偏差小于1 Nm。最后,通过台架实验结果反馈,进一步验证了模糊PID使直流电机的性能更加稳定和优化,从而得出该控制策略的实用价值。As a green vehicle,pure electric vehicle is coming into our life.The speed control system of electric vehicle is one of the key technologies of electric vehicle.In this paper,the fuzzy PID control strategy was added to the double closed-loop speed control system of DC motor.The whole vehicle model was established in Matlab/Simulink,and the control strategy was simulated in the starting,accelerating,uniform speed,braking conditions of the vehicle.The results show that the control strategy has good and stable dynamic and static characteristics for the motor speed control system,the speed deviation under each working condition is not more than 0.5 km/h,the time to reach the target speed is reduced by 20%,and the torque deviation is less than 1 Nm.Finally,through the feedback of bench test results,it further verified that the fuzzy PID made the performance of DC motor more stable and optimized,so as to obtain the practical value of the control strategy.
