典型模糊控制器的结构分析

Structure analysis of typical fuzzy controllers

为了研究模糊控制器的本质,本文推导了输入、输出隶属函数均采用等腰模糊数的一类双输入单输出模糊控制器的解析表达式,证明了这类模糊控制器相当于一个全局二维多值继电器与局部非线性PI控制器的和。

\ In order to study the essence of fuzzy controllers, a new isoceles fuzzy number membership function of the input and output variables is applied to design the structure of the typical fuzzy controller with two inputs and one output in this paperThe author analytically proves that a nonlinear fuzzy controller with linear rules is the sum of a global twodimensional multilevel relay and a local nonlinear proportionalintegral controller
