N2 - With the development of network, the wide use of network makes the state sensing more complex, and there inevitably exists the effect of network's uncertainty. In this paper, a new model which considers the state estimation with the network packet dropout is proposed and this is a robust state estimation problem. In this paper a robust state estimation based on quadratic programming(RSE-QP) method is proposed. In this algorithm, with the use of l1 term to describe and handle the packet dropout, there needs some transformations to express it as a standard l1 regularized least squares problem(LSP) for convenient and fast solving. Through solving a l 1 regularized LSP and associating with the Kalman filter updating procedure, the good estimated state is gained effectively even when there exists network packet dropout.
