带有EIFF的专家模糊控制器

The Fuzzy Controller with EIFE

基于L.A.ZADEH与E.H.MAMDAN的模糊控制原理,为微机实现方便,本文以具有解析式的模糊控制器为研究重点。通过对常规模糊控制器(FC)设计过程及控制机理分析后,提出了一种具有误差增量模糊化因子(EIFF)的专家控制器,解决了常规模糊控制器静、动态不能兼顾的缺点,常规仿真及变结构仿真证明,该控制器无论对于对象参数变化、结构变化还是系统白噪声、观测白噪声都具有很强的适应能力,控制策略具有一定的工程实用价值。最后给出了进一步的研究结果概要。

Based on L. A. YADEH and E. H. MAMDAN's fuzzy control theory, for simplicity of design and computer implement, fuzzy controller with analytic equation is used as a research point. Via scheme proof and simulation, a new kind of expert fuzzy controller with ERROR INCREMENT FUZZILY FACTOR(EIFF) is proposed. The performance of the step responr ce shows that this kind of controller ( EIFF controller) has a very strong robustness.
