无位置传感器的BLDCM的自调整免疫PID控制器研究

Research of Sensorless Brushless DC Motors Using Fuzzy Based Immune Feedback PID Control

采用免疫PID和传统PID相结合作为速度控制器,应用于无位置传感器无刷直流电机(BLDCM)的调速应用中。系统采用双闭环控制,内环为电流环,外环为速度环。Matlab仿真表明,系统超调量小,速度响应快,对外界干扰得到了很好的抑制,具有较好的控制精度和较好的鲁棒性,较之传统的PID控制,采用模糊免疫PID控制在无位置传感器BLDCM的控制中取得了较好的实验效果,具有较好的动态和静态性能。

An Immune Feedback PID controller combination with a general PID controller is used in Sensorless Brushless DC Motor speed servo system. The system includes current and speed closed loops. The simulation illustrates that excellent flexibility and adaptability as well as high precision and good robustness are obtained by the proposed strategy.
