摘要
对于一类状态不可测非线性互联时滞系统,给出一种基于观测器的模糊分散输出反馈控制方法.首先采用模糊T-S模型对非线性互联时滞系统进行模糊建模,在此基础上给出了模糊分散观测器和基于观测器的模糊分散输出控制器的设计.应用李亚普诺夫函数法和线性矩阵不等式方法给出了模糊分散控制系统稳定的充分条件.仿真结果进一步验证了所提出的模糊分散控制方法的有效性.
An observer based on fuzzy decentralized control method for a class of nonlinear interconnected systems with time-delay is proposed. An equivalent T-S fuzzy model is applied to the fuzzy modeling of the nonlinear interconnected system with time-delay , then the fuzzy decentralized observer and fuzzy decentralized controller are designed. The sufficient conditions for the stability of the fuzzy decentralized system with time-delay are proposed by using Lyapunov function combined with linear matrix inequalities (LMIs). Finally, the simulation results show the effectiveness of the proposed methods.
