Distributed Networked Controller Design for Large-Scale Systems Under Round-Robin Communication Protocol

This article studies the distributed L
₂
-gain control problem for continuous-time large-scale systems under Round-Robin communication protocol. In this protocol, each subcontroller obtains its own subsystem's state information continuously while communicating with neighbors at discrete-time instants periodically. Distributed controllers are designed such that the closed-loop system is exponentially stable and that the prescribed L
₂
-gain is satisfied. The design condition is obtained based on a time-delay approach and given in terms of linear matrix inequalities. Finally, three numerical examples are presented to illustrate the efficiency of the proposed scheme.
