摘要:

在本文中,我们研究了应用切换系统的稳定性准则来推导系统的时滞依赖条件的影响下,一个常数和一个时变时滞。我们的方法的主要新颖之处在于使用路径完整的李雅普诺夫技术以及一个新的修改功能的命题,以获得凸分析条件,同时避免了需要计算的停留时间为每个模式在切换系统表示,通常在\textit{switched approach}的时滞系统。此外,我们利用发达国家的分析,以获得线性矩阵不等式的闭环稳定的系统与时变传感器延迟通过基于补偿器。数值例子说明了所提出的方法。

英文摘要:

In this paper, we study the application of switched systems stability criteria to derive delay-dependent conditions for systems affected by both a constant and a time-varying delay. The main novelty of our approach lies on the use of path-complete Lyapunov techniques along with the proposition of a new modified functional to obtain convex analysis conditions while avoiding the need of computing a dwell time for each mode in a switched system representation, as usual in the \textit{switched approach} for time-delay systems. Furthermore, we leverage the developed analysis to obtain LMIs for the closed-loop stabilization of systems with time-varying sensor delays by means of an observer-based compensator. A numerical example illustrates the proposed methods.
