摘要

本文介绍了频域模糊超前相补偿器的分析与设计。模糊超前相位补偿器的主要特点是具有有效补偿控制系统相位特性的参数。通过引入频率特性的概念，给出了实现超前相补偿的一个重要定理。给出了两种模糊超前相位补偿器的设计方法:线性对象和未知非线性对象。将其中的一种设计方法应用于具有死时间的非线性系统——油罐液位控制。仿真结果表明了设计方法的有效性

Analysis and design of fuzzy controllers in frequency domain

This paper describes analysis and design of fuzzy phase-lead compensators in frequency domain. The main feature of fuzzy phase-lead compensators is to have parameters for effectively compensating phase characteristics in control systems. We show an important theorem, which realizes a phase-lead compensation, by introducing concept of frequency characteristics. Two design procedures of fuzzy phase-lead compensators are presented: cases of linear plant and unknown nonlinear plant. We apply one of the design procedures to tank level control which is a non linear system with dead time. Simulation results show validity of the design method.<>
