网络控制系统的时延相关状态反馈控制器设计

Delay-dependent state feedback controller design for a class of networked control systems

研究了具有时延、丢包和数据包时序错乱的网络控制系统镇定问题.为了有效提高系统的控制性能,本文根据网络控制系统的特点提出一种时延相关状态反馈控制方法,并将闭环网络控制系统建模为离散时间切换模型.在此基础上,通过构造依赖于参数的Lyapunov函数给出了闭环网络控制系统的稳定条件和镇定控制器设计方法.仿真结果和实验结果表明所提方法的有效性和可用性.

We investigate the stabilization problem for a class of networked control systems（NCSs） with time-delays,packet losses and out-of-order data.To improve the control performance of NCSs,we build a delay-dependent state feedback controller and transform the resulting closed-loop system into a discrete-time switched system.Under this framework,the stability conditions are derived by using the delay-dependent Lyapunov approach,and the design method for the corresponding stabilizing controller is developed.Simulation and experimental results are given to illustrate the effectiveness of the proposed method.
