摘要
为了解决基本模糊控制稳态精度欠佳的问题,提出无刷直流电机伺服系统积分自整定模糊控制器设计方法。该方法在基本模糊控制的基础上增加一个系数自整定积分器,根据实际工程经验并采用模糊控制规则确定积分因子,从而自动地调整积分系数。仿真结果表明,积分自整定模糊控制的动态和稳态性能均优于常规模糊控制。
In order to solve the problem of static precision characteristic of basic fuzzy control being not good enough, it is pro posed that design method of integration self adjusting fuzzy controller for brushless DC motor serve system. The method is increased the self- adjusting integrator based on basic fuzzy controller, and integral component is determined according to practical experience and fuzzy control rule. Integral parameters is adjusted automatically. The simulation results show the dynamics and static characteristic of integration self- adjusting fuzzy controller is superior to basic fuzzy controller.
