Stability analysis for time-varying networked control systems with multi-input and multi-output

This paper deals with the problem of stability for time-varying networked control systems with multiple state time-delays. In view of multi-input and multi-output networked control systems (NCSs) with many independent sensors and actuators, a continuous time model of time-varying NCSs with distributed time-delays is proposed. Based on the Lyapunov function method, the sufficient delay-dependent conditions for the exponential stability with a given convergence rate are given, which are described in terms of linear matrix inequalities (LMIs) and the solution of Riccati differential equations (RDEs). Numerical examples are given to illustrate the results.
