This paper considers the output feedback ${\mathcal{L}}_2$-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 ${\mathcal{L}}_2$-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.

本文考虑输出反馈 ${\mathcal{升}}_2$- 受循环协议约束的连续时间网络控制系统的增益控制问题。所考虑系统的传感器分布在网络上。引入循环协议来调度从传感器传输到控制器的测量信息。然后将闭环系统建模为一种时滞系统。根据 Lyapunov-Krasovskii 方法，推导出充分条件来保证指数稳定性和规定的${\mathcal{升}}_2$- 闭环系统的增益。通过求解线性矩阵不等式，可以有效地确定输出反馈控制器增益。最后，报告了一个例子来说明所提出的设计方案的优点。
