基于模糊PI控制的无刷直流电机调速系统仿真

针对传统PI控制方法在对稀土永磁无刷直流电动机进行控制时鲁棒性差、精度低等缺点,提出了一种参数自整定模糊PI控制方法,即采用传统的PI控制与模糊控制相结合的新型控制方法。将方法应用于永磁无刷直流电动机双闭环调速系统的转速闭环中,并利用MATLAB软件中的模糊控制工具箱进行了系统的辅助设计与仿真。仿真结果表明,参数自整定模糊PI控制方法改善了电机的动静态性能,系统的鲁棒性和精度也大大提高。

Simulation of BLDCM Speed Control System Based on Fuzzy-PI Control Method

In this paper,a new method based on fuzzy self-adapting PI control is presented which is suitable for BLDCM.This method overcomes some defects of traditional PI control.A design method for fuzzy self-adapting PI controller is given,and it is applied to the system of a speed closed-loop in BLDCM double closed-loop system.Then an example of how to design and simulate the system by using the software MATLAB is introduced.The results of simulation show that the performance is superior to that of the traditional...
