| 摘 要： | 为了改善无刷直流电机的调速性能,针对普通模糊PID速度控制器的缺陷,研究了基于变论域思想的自适应模糊PID控制器及其在BLDCM控制系统中的应用.在Matlab仿真平台下,建立了BLDCM的模型,构建了BLDCM的电流、转速双闭环控制系统,其中转速环采用了变论域自适应模糊PID控制器,电流环采用普通PID控制器.仿真结果表明,与常规PID控制器和普通模糊PID相比,采用变论域自适应模糊PID控制器的优势在于:转速输出无超调、响应速度快、控制精度高,具有较强的鲁棒性和自适应能力.

| Abstract: | In order to improve the timing performance of brushless DC motor(BLDCM in brief),and in view of the shortages of the normal fuzzy controller,the paper investigates variable universe fuzzy adaptive PID(VU-Fuzzy PID in brief) controller used in BLDCM control system.Based on Matlab,the model of BLDCM is built up and the simulation system of BLDCM with double loop controller was established.The speed loop was controlled by the VU-Fuzzy PID controller and the current loop was controlled by the common PID control... |
