摘要
This paper studies the optimal output tracking control and stabilization for networked control systems with packet losses via output feedback control.Both finite-horizon and infinite-horizon cases are considered.For the finite-horizon case,the authors introduce an augmented system according to the state variable and the reference trajectory for the first time.Based on a set of difference Riccati equations,an optimal output feedback tracking controller is proposed by applying the stochastic maximum principle.And an optimal estimator is presented.For the infinite-horizon case,a necessary and sufficient condition for the stabilization of the system is provided.And an optimal output feedback stabilizing tracking controller is obtained by establishing a set of algebraic Riccati equations.Finally,numerical examples are given to verify the proposed results.
