摘 要: | 针对电动汽车行驶工况的要求,为了使电机能够有良好的启动特性和稳态特性,在Simulink中建立了无刷直流电机转速-电流双闭环控制系统仿真模型,转速控制神经网络和模糊控制对PID控制参数进行在线整定;电流环采用电流滞环控制,并对控制模型进行空载启动后加载实验。实验结果表明,本文设计的控制系统响应速度快,无静差,抗干扰能力强。

Abstract: | In response to the requirements of electric vehicle driving conditions,in order to enable the motor to have good starting characteristics and steady-state characteristics,a brushless DC motor speed-current double closed-loop control system simulation model,speed control neural network and fuzzy control system are established in Simulink.The control performs online tuning of PID control parameters;the current loop adopts current hysteresis control,and the control model is loaded after no-load startup.The experimental results show that the control system designed in this paper has fast response speed,no static error,and strong anti-interference ability. |
