摘要
针对遵循轮叫调度协议的时延网络控制系统,研究了系统在不等间隔采样下的鲁棒H_∞控制。首先,建立了遵循轮叫调度协议的网络控制系统在不等间隔采样下的系统切换模型。通过运用Lyapunov-Krasovskii泛函和鲁棒H_∞控制理论,得到了闭环系统时延依赖稳定性判据。然后,把结论推广到了不确定网络控制系统,并获得了系统的时延依赖稳定性判据。最后,通过一个与其他文献方法相比的实例,说明了该方法的可行性和先进性。
For a class of time-delay network control systems under Round-Robin scheduling protocol, robust H∞ control of the system under unequal interval samplings is studied in this paper. First of all, the switched system is established for the network control systems under the round robin scheduling protocol and the unequal interval sampling. A delay-dependent stability criterion for networked control systems is obtained through using Lyapunov-Krasovskii functional and robust H∞ control theory. Next, a stability criterion for uncertain network control systems is obtained via derivations. Finally, through compared with some methods of other literature, an example is given to illustrate the feasibility and advancement of the presented method.
