退化时滞系统的降维泛函观测器设计

State functional observer design for linear descriptor systems with delay

讨论退化时滞系统观测器的设计方法.首先利用时滞算子将系统改写为算子方程的形式,然后通过矩阵变换将系统转化为维数为n-r的不含退化的系统而且输出为x1,在可观测条件下,可以得到退化时滞系统的降维泛函观测器.

An observer design was proposed for linear descriptor systems with time delay. Firstly, we found a coordinate matrix change such that the new system was a normal reduced order system and the output was the state x1 .Then guaranteed by a rank condition on the observability matrix, we could obtain an observer for descriptor systems with time delay.
