对于网络控制系统中的状态估计,网络链路上丢包的影响是一个重要问题。在本文中,我们引入多重描述(MD)源编码方案来提高卡尔曼滤波器在丢包情况下估计误差协方差的统计稳定性和性能。我们考虑两种情况:当网络链路上的数据包丢失发生在独立同分布中时。时尚或突发时尚。与传统的单描述源编码相比,MD编码方案在两种情况下都可以极大地提高卡尔曼滤波器在大量丢包场景下的性能。
For state estimation in networked control systems, the impact of packet dropping over network links is an important problem. In this paper, we introduce multiple description (MD) source coding scheme to improve the statistical stability and performance of the estimation error covariance of Kalman filter with packet loss. We consider about two cases: when the packet loss over network links occurs in an i.i.d. fashion or in a bursty fashion. Compared with the traditional single description source coding, MD coding scheme can greatly improve the performance of Kalman filter over a large set of packet loss scenarios in both cases.
