摘　　要：针对含有不确定输入的广义时滞系统,研究输出函数观测器的设计方法。首先给出系统存在输出函数观测器的充分条件,其次通过线性矩阵不等式的方法求解观测器的各个参数,最后得出输出函数观测器设计的具体步骤。两个数值例子可以说明该方法的简单、有效性。The problem of functional observer design for a class of linear singular systems with delayed state and unknown input is considered.Firstly,sufficient conditions for the existence of this kind of observers are established.Secondly,in terms of linear matrix inequality approach,the functional observer can be obtained.Finally,the detailed steps to design the functional observer are shown.Numerical examples are given to illustrate the feasibility of the obtained results.
