A Dwell Time Switching Approach to Channel Assignment for Stabilization of NCSs With Medium Access Constraint

This paper investigated the networked control of a collection of continuous-time linear time-invariant plants with medium access constraints. We aim to stabilize the plants by effectively assigning the wireless channels and properly designing feedback controllers. By modeling the plant as a switched system and using a time-scheduled Lyapunov function approach, computable sufficient conditions on the stabilization and schedulability requirements are proposed in the framework of dwell time. Then, based on the results, an interesting channel assignment policy is obtained and time-scheduled state feedback controller design schemes are given. The effectiveness of the results is demonstrated by numerical simulations.
