离散模糊系统的新型模糊控制器与观测器设计

基于T－S模糊动态模型，研究了一类在状态空间形式下，离散模糊系统的稳定监督控制器的设计与分析，将全局模糊型按隶属函数重新划分成若干子空间，采用分段Lyapunov函数法，克服了以往设计法中需要求解一公共正定矩阵P的不足，也无需求解繁琐的Riccati方程，并针对系统状态不可测的实际情况，设计了模糊观测器，从而用成熟的线性系统理论完成对复杂非线性系统的控制，模糊控制器与观测器设计简单，适合工程应用。

Design of Discrete Fuzzy System Using New Fuzzy Controller and Observer

Based on T-S fuzzy dynamitic model, the design analysis for discrete system using linear supervise controller in state space framework, has been studied. The global fuzzy model has been newly divided into some subspace by membership. Using subsection Lyapunov function method, the defect of solving a common positive matrix P in formerly is overcome and the Riccati equation in trouble needs not to be solved. The fuzzy observer is designed for system in which has immeasurable state variable in general. It is completed by using mature linear system theory to control complex nonlinear system. The fuzzy controller and observer are simple, and suit for engineering use.
