摘要
讨论网络控制系统的状态反馈控制器设计问题。针对具有未知时变时延的网络控制系统,应用自由权矩阵方法得到系统的稳定性条件,并应用到具有时变结构不确定性的网络控制系统,在此基础上提出状态反馈控制器设计方法。数值实例表明该方法的有效性,与已有方法相比,具有较低的保守性。
This paper is concerned with the controller design of networked control systems (NCSs). For an NCS with unknown time-varying delay, the free-weighting matrix approach is employed to obtain stability conditions. Moreover, the conditions are applied to deal with the NCSs with time-varying structured uncertainties. As a result, a design method of state feedback controller is proposed. A numerical example is given to demonstrate the effectiveness and the less conservativeness over the existing methods.
