Stability criteria and output feedback controller design for MIMO networked control systems with network constraints

This paper is concerned with the stability analysis and controller design for a class of MIMO networked control systems (NCSs) with network constraints. In view of MIMO NCSs where network is of limited access channels, a discrete-time switched delay model is formulated. By constructing a novel switched Lyapunov-Krasovskii functional, a new stability criterion is developed in terms of linear matrix inequalities. On the basis of the obtained stability condition, a static output feedback controller is designed by applying an iterative algorithm. A numerical example is given to show the effectiveness of the proposed method.
