模糊PID控制器在无刷直流电机控制系统中的应用

Application of Fuzzy Adaptive PID Controller for Control System of BLDCM

无刷直流电机是一种多变量、非线性的控制系统,采用经典的PID控制难以达到满意的控制效果。将模糊自适应PID控制器应用于无刷直流电机的控制中,运用模糊控制原理对PID参数进行在线调整。实验结果表明,较之传统的PID控制,采用模糊自适应PID控制的无刷直流电机控制系统具有更好的动态和静态性能,达到了较好的控制效果。

[Abstract]Brushless DC motor （ BLDCM is a multi variable and non linear system, using conventional PID control can not obtain satisfied control effect. The application of fuzzy adaptive PID controller for control system of BLDCM and parameters self-tuning non-line by employing fuzzy control principle were introduced. The experiments illustrate that t he excellent static and dynamic performance compared with t he conventional PID control are achieved.
