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。
Aiming at a class of uncertain discrete nonlinear large-scale systems described by TS fuzzy model, the parallel distributed compensation method of state feedback is used to study the robust non-fragile guaranteed fuzzy control problem. In the presence of additive perturbation, , The closed-loop performance index value is lower than the defined upper bound. Using the method of linear matrix inequality (LMI), the existence conditions of non-fragile guaranteed fuzzy fuzzy control law are derived. The simulation results show that the design method is feasible and effective.
