Abstract

The paper presents conditions suitable in design of state observers for a class of continuous-time nonlinear systems with unknown input, represented by Takagi-Sugeno models with unmeasurable premise variables. Based on Lyapunov inequality, the conditions are outlined in the terms of linear matrix inequalities to possess a stable structure closest to optimal asymptotic properties. Simulation results illustrate the design procedure and demonstrate the basic performances of the proposed observer design method.

一类未知扰动非线性系统的Takagi-Sugeno模型状态估计
本文给出了一类具有不可测前提变量的Takagi-Sugeno模型的未知输入连续非线性系统的状态观测器设计的适用条件。基于Lyapunov不等式,用线性矩阵不等式的形式给出了具有最优渐近性质的稳定结构的条件。仿真结果说明了设计过程,并验证了所提观测器设计方法的基本性能。
