On MPC of linear system over networks with bounded delays and packet losses

Abstract

This paper studies the model predictive control (MPC) of the networked control systems (NCSs) where arbitrary bounded deterministic network-induced delays and packet losses may occur in both sensor to controller and controller to actuator links. A new augmented model, which is specially suitable to the on-line refreshed control law, is proposed, based on which an approach of networked MPC is proposed by extending the previous one for NCS with only packet losses. It is shown that closed-loop stability is guaranteed by the proposed approach, satisfying the input and state constraints. A numerical example is given to illustrate the effectiveness of the proposed MPC.
