This paper is to study the linear minimum variance estimation for discretetime systems. A simple approach to the problem is presented by developing re-organized innovation analysis for the systems with instantaneous and double time-delayed measurements. It is shown that the derived estimator involves solving three different standard Kalman filtering with the same dimension as the original system. The obtained results form the basis for solving some complicated problems such as H, fixed-lag smoothing, preview control, H, filtering and control with time delays.

Optimal Filtering for Delay System with Multiplicative Noise

Optimal Filtering for Delay System with Multiplicative Noise

第25届中国控制会议

作者： Lu Xiao, Zhang Huanshui, Wang Wei , Wang Wei Research Center of Information and Control, Dalian University of Technology, Dalian 116023, China Shenzhen Graduate School, Harbin Institute of Technology, Shenzhen 518055, China

＜正＞The paper deals with the Kalman filtering problem for linear discrete-time systems with parametric uncertainty of multiplicative noise in both instantaneous and delayed measurements. Although the problem may be addressed by applying an existing Kalman filtering technique to an augmented system, the computation of the Kalman filter could be demanding. To improve the efficiency of computation, we propose a new approach through the re-organization of innovation. The calculation of the optimal filter involves two Riccati equations associated with the Kalman filter of a delay-free system and the instantaneous measurement, respectively. The Riccati equations have the same dimension as the system.
