Abstract

In this article, the dynamic event-triggered output feedback control problem for a class of uncertain nonlinear systems is studied. Since system states are not available for controller design, a state observer is designed to estimate them. On the basis of the estimated states, a dynamic event-triggered control scheme is proposed. Compared with existing event-triggered schemes, a dynamic auxiliary variable is added in the event conditions. By properly designing the dynamics of the auxiliary variable, it is proved that the tracking/stabilization error is able to converge to zero without the presence of Zeno behavior. The effectiveness of the control scheme is verified by simulation results.

一类不确定非线性系统的动态事件触发输出反馈控制

研究了一类不确定非线性系统的动态事件触发输出反馈控制问题。由于系统状态在控制器设计中不可用，所以设计了一个状态观测器来估计它们。在估计状态的基础上，提出了一种动态事件触发控制方案。与现有的事件触发方案相比，在事件条件中增加了一个动态辅助变量。通过合理设计辅助变量的动力学特性，证明了在不存在芝诺行为的情况下，跟踪/镇定误差能够收敛到零。仿真结果验证了该控制方案的有效性。

期刊介绍： Papers that do not include an element of robust or nonlinear control and estimation theory will not be considered by the journal, and all papers will be expected to include significant novel content. The focus of the journal is on model based control design approaches rather than heuristic or rule based methods. Papers on neural networks will have to be of exceptional novelty to be considered for the journal.
