摘要: This talk discusses some compensation schemes for remote state estimation. To deal with the uncontrollable packet loss existing in the channel connecting the local sensorand the remote estimator, a novel mechanism called linear temporal coding isproposed,in which the linear combination of the current measurement and the one of thelast step is used. For the case that the packet arrival sequence is unavailable, a noveltwo-stage estimation algorithm is proposed using innovation sequence approach.When measurement noise plays the dominating role, simulations show the benefit ofusing measurement combination; in contrary, when communication noise plays thedominating role, we prove that there is no benefit to use such a coding scheme for first-ordersystems. For the case that the packet arrival sequence is available, an on-line compensationscheme is proposed. A novel state observer is designed to better reveal the recursiverelationshipsof the error covariance. The equivalency of the two expressions is also verifiedand the optimal coding weight is further obtained for first-order systems.
