摘　　要：讨论广义时滞系统的降维观测器的设计方法.通过引入矩阵的广义逆矩阵,给出在一定条件下降维观测器的具体形式,然后分别利用广义逆矩阵及Lyapunov函数方法给出这些条件成立的具体条件及验证方法。最后给出一个例子来说明方法的有效性。In this paper, we discuss the new design method of state observer for linear descriptor systems with delay. Generalized in verse matrix is introdnced to the observer design, based on generalined inverse matrix, we give the concrete form of state observer under some conditions, and then use generalized inverse matrix and Lyapunov function to present how these conditions can hold, At last, a example shows the effectiveness of the proposed approach.
