摘　　要：针对一类具有线性不确定时滞系统带有一定约束的鲁棒最优保成本控制器设计问题.利用线性矩阵不等式,构造了一系统二次性能指标的上界,此上界满足要求的不确定参数来说是鲁棒的,同时给出了最优控制器设计方法和数值例子说明该方法的有效性.As for a class of linear uncertain time-delay system with certain constraints Robust optimal guaranteed cost controller design problem,this paper uses linear matrix inequalities,to construct a system of the upper bound of quadrtic performance index.The uncertain parameters of which this upper bound meets the requirements is robust.At the same time optimal controller design method is given.Numerical examples show the effectiveness of the method.
