研究了一类执行器饱和非线性Hamilton网络控制系统H∞状态反馈控制器设计问题。该类网络控制系统中存在不确定的网络时延及丢包,待设计的控制器受到饱和因素的约束,且系统的外部扰动范数有界但统计特性未知。结合Hamilton系统结构特性,当网络时延和连续丢包有界时,将网络时延和连续丢包转化为时变时滞,应用Lyapunov-Krasovskii稳定性理论来分析和设计H∞控制器,使其满足H∞性能指标,控制器中的未知参数通过求解不等式来确定。算例分析与仿真验证了方法的有效性。 The design problem of H∞ state feedback controller for a class of actuator-saturated nonlinear Hamilton networked control systems is studied. The network control system has uncertain network delay and packet loss. The controller to be designed is constrained by the saturation factor, and the system’s external disturbance norm is bounded but the statistical properties are unknown. Combined with the structural characteristics of Hamilton system, the network delay and continuous packet loss are transformed into time-varying delay when the network delay and continuous packet loss are positive. The Lyapunov-Krasovskii stability theory is used to analyze and design the H∞ controller It satisfies the H∞ performance index, and the unknown parameter in the controller is determined by solving the inequality. The example analysis and simulation verify the effectiveness of the method.
