Distributed control of MIMO networked control systems with time-triggered protocol

In recent years, networked control systems (NCSs) research has attracted a lot of interests, and many results on single closed-loop scenario are delivered. For large scale NCSs, distributed control is more suitable than centralized control. This article introduces a distributed control approach for a class of NCSs with multiple subsystems based on a time-triggered network. Firstly, time-triggered protocol and schedule strategy are introduced. Then a novel model is proposed for NCSs with network induced delay and data packet loss. The resulting closed-loop system is a jump linear system under a distributed control law with state feedback. A stability criterion is presented based on a Lyapunov-Krasovskii function and matrix inequalities. Also a controller design approach is given using cone complement linearization and an iterative algorithm. Finally, a numerical example is given to validate the approach.
