无刷直流电机模糊PID控制系统研究与仿真

针对传统PID控制方法在对无刷直流电动机进行控制时精度低、抗干扰能力差等缺点,提出了一种参数自适应模糊PID控制方法。首先建立了无刷直流电机的动态数学模型,并对其转速进行模糊PID控制。介绍了模糊PID控制器的设计方法,应用MATLAB实现了系统设计和仿真。最后对PID控制和模糊PID控制的仿真结果进行对比分析,结果表明:模糊PID控制方法使无刷直流电机控制系统具有更好的动、静态性能和抗干扰能力。

Study and Simulation of Fuzzy - PID Control System of BLDCM

This paper presented a new method based on the Fuzzy self-adaptive PID for BLDCM.This method overcomes some defects of the traditional PID control,such as lower control precision and worse anti-jamming performance.At first,the dynamic model of BLDCM was built,and the speed was contolled by Fuzzy-PID control.Then,the paper presented the method of how to design the Fuzzy-PID controller and implemented the design and simulation of the system by the MATLAB software.At last,it compared simulation results of PID control method with Fuzzy-PID control method.The results show that the Fuzzy-PID control method has more excellent dynamic and static performances,as well as anti-jamming performance.
