摘要
针对一类用T-S模糊模型描述的不确定离散非线性大系统,采用状态反馈的并行分布补偿方法研究其鲁棒非脆弱保性能模糊控制问题,使得在控制器存在可加性摄动的情况下,其闭环性能指标值低于确定的上界。利用线性矩阵不等式处理方法,导出了非脆弱保性能模糊控制律的存在条件。实例仿真结果表明了该设计方法的可行性和有效性。
A robust non-fragile guaranteed cost fuzzy control problem for a class of uncertain discrete-time nonlinear large- scale systems described by T-S fuzzy model is presented. The objective is to design a non-fragile guaranteed cost state feedback controller via the parallel distributed compensation（ PDC） approach such that the closed-loop system is asymptotically stable and the closed-loop performance is no more than a certain upper bound in the presence of the additive controller gain perturbations. A sufficient condition for the existence of such non-fragile guaranteed cost controllers is derived via the linear matrix inequality （LMI） approach. Simulation results demonstrate the feasibility and the effectiveneas of the proposed design.
