摘要
永磁无刷直流电动机调速系统是一个非线性、多变量、时变系统。采用传统的PID控制方法进行控制，难以达到良好的控制效果。通过设计一种模糊PID控制器，应用模糊算法在线自动整定PID参数的方法，将其应用于无刷直流电动机调速控制系统。仿真实验结果表明，该模糊PID控制方法较常规PID控制和单纯的模糊控制具有更好的控制性能，具有无超调、响应快、鲁棒性强等特点。
System of BLDCM is a non -linear , multi -variable , time -varying system.Using the traditional method for PID control is difficult to achieve fine control effection. By designing a fuzzy PID controller,fuzzy algorithm for on-line auto-tuning PID parameters is applied to the BLDCM speed control system. The simulation results show that the method of fuzzy PID control has better control performance, and has characteristics of no overshoot,fast response and robustness conventional PID control.
