摘要
基于T-S模糊模型,研究一类具有状态和输入滞后的不确定奇异系统的模糊保成本控制问题.基于线性矩阵不等式(LMI)的可解性,给出了状态反馈保成本控制器存在的充分条件,该条件保证闭环系统是二次型稳定的,还能获得闭环成本值的上界,所有结果均以线性矩阵不等式的形式给出.数值仿真结果表明该方法是有效的.
Based on T-S fuzzy model,the robust guaranteed cost control problem is studied for a class of uncertain singular system with state and input delays.Sufficient conditions are provided for the construction of a state feedback guaranteed cost controller.These conditions are given in terms of the feasibility of linear matrix inequalities（LMI） and guarantee that the closed-loop systems are quadratically stable.Moreover,an upper bound of the guaranteed cost is also obtained.A numerical example is provided to demonstrate the effectiveness of the proposed method.
