基于模糊PID控制的永磁无刷直流电动机调速系统研究

Study of the Performance of BLDCM System Based on Fuzzy-PID Control

针对传统PID控制的一些缺点,提出了一种永磁无刷直流电动机调速系统模糊PID控制方法,介绍了模糊PID控制器的设计方法,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实验。仿真结果表明,该方法可使电机调速系统性能得到提高。

In this paper, a new method based on Fuzzy-PID control is presented which is suitable for BLDCM. This method overcomes some defects of traditional PID control. A designing method of Fuzzy-PID controller is given, and an example of how to design and simulate the system by using the software MATLAB is introduced. The simulation results show the performance of BLDCM system is improved by using the proposed controller.
