Study of the Fuzzy PID Control Strategy of Brushless DC Motor Based on SIMULINK

在分析方波型永磁无刷直流电动机(BLDCM)数学模型的基础上,针对典型的两相导通星型三相六状态工作方式的无刷直流电动机,提出了一种模糊PID控制方法,在Matlab/Simulink平台上建立了无刷直流电机模糊PID控制策略的仿真模型,改变参数后,对其也进行了仿真,并且将模糊PID控制和传统PID控制的控制效果进行了比较。仿真结果表明:建立的该系统具有鲁棒性强、响应速度快、无超调,且稳态精度高等优点。

Based on analyzing the mathematical model of square-wave brushless DC motor,aiming at the typical operating mode of the 2-phase turn-on 3-phase 6-state with wye-connected,the paper proposes a fuzzy PID control strategy.A fuzzy PID control strategy simulation model is established on Matlab/Simulink platform and then fuzzy PID of brushless DC motor model is also simulated by changing parameters.The control results are compared with that of fuzzy PID and conventional PID control.The results of simulation indicate that the system has the advantages of strong robustness,fast response time and high steady-state accuracy.
