This paper addresses the synthesis approach of model predictive control (MPC) for the constrained linear systems under networked environment where both data quantization and packet loss may occur. Based on a previous approach which considers packet loss only, this paper proposes an extended approach which incorporates data quantization effect. Technically, the infinite horizon control moves are parameterized into a single state feedback law, at each sampling instant, and the robust stability is specified for all possible packet losses and quantization errors. Both the closed-loop model and the resultant optimization problem include the previous packet-loss-only results as special cases. A numerical example is given to illustrate the effectiveness of the developed MPC. (c) 2013 Elsevier Ltd. All rights reserved.
