Periodic event-triggered impulsive control for a class of uncertain nonlinear systems

第43届中国控制会议

作者： Fei Feng Xingwen Liu jinnan luo Center for Intelligent Complex Systems College of Electrical Engineering Southwest Minzu University

This paper addresses the issue of exponential stability of discrete-time almost periodic piecewise linear systems(APPLSs) with dwell time uncertainties under mode-dependent average dwell time(MDADT) switching signal. Considering dwell time uncertainties in discrete-time APPLSs, multiple piecewise convex homogeneous Lyapunov function(MPCHLF) is constructed. In the case where the switching instants within each period are unknown but lie within a certain range, a sufficient exponential stability condition for the discrete-time systems is proposed. Finally, a numerical example validates obtaining low conservatism using the proposed approach.

随着老龄化程度的加深,居家养老正逐渐发展成我国的主流养老模式。构建适应区域老龄化特征的居家养老服务模式是积极应对老龄化的现实选择,是应对养老资源分布不均衡的理性策略。文章基于对辽宁省部分地区养老服务政策的分析,结合对三种典型居家养老服务模式的剖析发现:目前居家养老服务主要是以政府主导为原则,鼓励社会组织和公众参与,一定程度上满足了老年人的基本生存和安全需要;在实施居家养老服务的过程中,仍存在“重城市轻农村”“重普遍轻特殊”和“重服务轻资源”的不平衡现象。对此,文章认为应在居家养老服务模式中引入社会工作服务,通过填补农村养老空白领域、精准把握特殊群体需求和蓄积社会工作资源,为完善居家养老服务政策提供新思路。

Quantum entanglement, referred to as “spooky action at a distance” by Einstein, is not only an intriguing and fascinating feature of quantum theory challenging our classical intuitions about locality and correlations, but also has practical and profound implications for quantum technologies. Initially described by Einstein, Podolsky and Rosen, as well as by Schro¨dinger, entanglement now has become a basic and crucial ingredient for both foundational and experimental investigations of the quantum world.
