Abstract

This paper is concerned with the design of the optimal linear filter for a networked descriptor system with multiple packet losses. A descriptor system is converted to two reduced-order subsystems. Based on projection theory, the optimal linear filters for the two reduced-order subsystems with packet losses are presented in the linear minimum variance sense, respectively. Further, the linear filter for the original descriptor system is obtained. The proposed filter only depends on the data arrival rate but do not depend on the knowledge whether the sensor data are received at a particular time. A simulation example shows its effectiveness.
