Output feedback L2-gain control of networked control systems subject to round-robin protocol

This paper considers the output feedback L-2-gain control problem for continuous-time networked control systems subject to round-robin protocol. The sensors of the considered system are distributed over a network. Round-robin protocol is introduced to schedule the measurement information transmitted from sensors to the controller. Then the closed-loop system is modeled as a kind of time-delay system. According to Lyapunov-Krasovskii method, sufficient conditions are derived to guarantee the exponential stability and the prescribed L-2-gain of the closed-loop system. The output feedback controller gains are determined efficiently by solving linear matrix inequalities. Finally, one example is reported to illustrate the advantages of the proposed design scheme.
