基于参数可变PID控制器的永磁无刷直流电机转速控制系统
Speed Control System of Permanent Magnet Brushless DC Motor Based on Variable Parameter PID Controller
摘要
Abstract
As permanent magnet brushless DC motor (BLDCM) is a motor of multivariable,nonlinearity and time-varying,The conventional PID control is difficult to achieve the high precision and high performance requirements on modern industrial control.Based on the analysis of dynamic mathematical model of speed control system for BLDCM,combined with genetic algorithm to search the global optimal value,the BLDCM speed control of variable parameter PI controller was proposed.The results of software simulation and prototype test showed that the PID controller of GA optimization haed better control performance,with no overshoot,fast response,strong robustness and so on,so as to achieve the precise control of the speed.关键词
