时延相关网络控制系统的输出反馈镇定

Delay-Dependent Output Feedback Stabilization of Networked Control Systems

研究了一类具有时变时延网络控制系统的输出反馈镇定问题.对于传感器与控制器间产生时变时延情形,采用时延相关切换控制器,通过Lyapunov-Krasovskii泛函方法和广义模型变换,得到了使闭环系统渐近稳定的线性矩阵不等式充分条件,该控制器是可以降阶的.仿真算例验证了该方法的有效性.

The problem of delay-dependent stabilization for networked control system with time-varying delay is dis- cussed. For time-varying delays occurring between sensor to controller, by constructing a delay-dependent switched controller, a novel Lyapunov-Krasovskii functional and descriptor system method , a sufficient condition for the sys- tem to be asymptotically stable is established in terms of LMIs, and the controller can be reduced order. A numeri- cal example is given to illustrate the effectiveness of the presented method.
