摘要: 基于Zadeh的模糊逻辑推理和语言控制策略,进行了三维模糊控制器的结构研 究.证明了具有线性控制规则的三维模糊控制器可等同于一个全局多层次线性关系式和一 个局部非线性PID型控制器,由此剖析了模糊控制器的推理机制和其非线性本质.Abstract: Based on Zadeh's linguistic control strategy and inference process, this paper presents an approach to the structure analysis of three-dimensional fuzzy controller. The authors analytically prove that a typical three-dimensional fuzzy controller with linear control rules is the sum of a global nonlinear controller and a local nonlinear PID-like controller. In such a way, the reasoning mechanism of three-dimensional fuzzy controller is presented and the nonlinear essence of it disclosed.
