针对具有有界时滞且时滞上界大于一个采样周期的网络控制系统,研究了系统建模和状态反馈镇定问题.在分析有界时滞的所有可能性的基础上,提出一种能够用于处理时变控制律问题的网络控制系统数学模型,进而将该系统的镇定问题转化为镇定一系列模型的鲁棒控制问题.根据Lyapunov方法,给出了保证闭环系统稳定的状态反馈控制器.仿真算例验证了所提出方法的有效性. For networked control systems with bounded time-delay and upper-bound of delay greater than one sampling period, the problems of system modeling and state feedback stabilization are studied. Based on the analysis of all possibilities of bounded time-delay, In order to solve the robust control problem of a series of models, the state feedback controller which guarantees the stability of the closed-loop system is given according to the Lyapunov method. Simulation results show the effectiveness of the proposed method.
