自校正模糊控制器的设计

Design of Self Adjusting Fuzzy Controller

综合Ｍ．ＳＵＧＥＮＯ和Ｇ．Ｔ．ＫＡＮＧ的设计思想，提出了利用控制作用模式化方程设计自校正模糊控制器的方法．系统地介绍了自校正模糊控制器的结构、控制算法分析及状态变量论域参数的自校正算法，同时给出了有关数字仿真结果．数字仿真结果表明，自校正模糊控制器在响应速度、调节时间和稳态精度这几个品质参数上基本达到了常规ＰＩＤ优化控制的效果，且比常规ＰＩＤ控制具有更强的适应性。

Based on the idea of M. Sugeno and G. T. Kang, a quantitative method for the design of self adjusting fuzzy controller is presented. The structure and control algorithm with self adjusting parameters are described in detail. The results of emulation prove that the new method is preferable to the conventional PID control algorithm and more suitable for the cases in which precise mathematical model is unknown or system parameters are unstable.
