摘要: 主要研究了带有时滞的非线性系统基于事件触发的状态估计器.首先,利用事件触发机制建立系统中的状态估计器,并用Lyapunov函数使系统在有限时间内均方有界.其次,基于H∞有界条件,得到了有限时间内系统H∞有界准则.最后,通过一个数值例子说明了所得结果的有效性.Abstract: The event-triggered state estimator for nonlinear systems with time delay was studied. Firstly, the state estimator for nonlinear systems was established by the event-triggered mechanism, and the Lyapunov function was used to make the system mean square bounded in finite time. Secondly, based on the H∞ bounded condition, the system’s H∞ finite time bounded criterion was obtained. Finally, a numerical example was given to illustrate the validity of the obtained result.
