摘要

本文探讨了为受外部干扰的二阶矢量系统设计事件触发自然二阶状态观测器的问题。在这项工作中，利用事件触发条件满足时的离散测量来构建状态观测器。由于使用事件触发机制和外部扰动会产生误差，本文的方法只能稳健地估计二阶矢量观测器的状态位置和状态速度，而不是渐进地估计它们。本文在研究自然二阶观测器动态误差系统的稳定性时，没有使用基于参数相关 Lyapunov 函数的方法，而是建立了一个凸优化问题，给出了事件触发机制和最小化水平，以评估事件触发自然二阶观测器动态误差系统的有界性。一个汽车悬架和两个数值实例证明了所提方法的有效性。

Design of event-triggered natural second-order observers for second-order vector systems

The problem of designing event-triggered natural second-order state observers for second-order vector systems subject to external disturbances is considered in this paper. In this work, state observer is constructed using discrete measurements at instants when an event-triggered condition is satisfied. Due to the errors that arise by using the event-triggered mechanism and the external disturbance, the method in this paper only robustly estimates the state position and the state velocity of the second-order vector observers instead of estimating them asymptotically. Instead of using the method based on a parameter-dependent Lyapunov function in investigating the stability of the dynamic error system of natural second-order observers, a convex optimization problem is established in this paper to give an event-triggered mechanism and minimized levels in evaluating the boundedness of the dynamic error system of the event-triggered natural second-order observers. An automobile suspension and two numerical examples demonstrate the effectiveness of the proposed method.

期刊介绍： Systems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes."
