摘要

研究了具有延迟输出测量值的切换离散线性系统的有限时间精确估计问题。首先，建立了具有延迟输出的线性系统的精确估计和有限时间估计的结果。然后，将其扩展到切换系统、切换奇异系统和未知输入切换系统。提出了两种估计算法：第一种是基于系统状态的显式计算，采用延迟输入/输出与反向替换技术相结合的组合；第二种方法使用两个满足共同数学关系的状态观测器。在此基础上，给出了基于上述估计算法的输出反馈镇定方案。给出了实际模型的实例来说明算法的有效性。

Estimation and output feedback stabilization for switched linear discrete-time systems with delayed-outputs

This paper addresses the problem of exact finite-time estimation for switched discrete-time linear systems with delayed output measurements. First, results on exact and finite-time estimation of linear systems with delayed outputs are established. Then, extensions to switched systems, switched singular systems, and switched systems with unknown input are developed. Two estimation algorithms are proposed: the first is based on an explicit computation of the system state by using a combination of delayed inputs/outputs jointly with the backward substitution technique; the second uses two state observers satisfying a common mathematical relation. Furthermore, output feedback stabilization schemes based on the aforementioned estimation algorithms are provided. Illustrations of real-world models are provided to show the efficiency of the algorithms.

期刊介绍： The European Control Association (EUCA) has among its objectives to promote the development of the discipline. Apart from the European Control Conferences, the European Journal of Control is the Association''s main channel for the dissemination of important contributions in the field. The aim of the Journal is to publish high quality papers on the theory and practice of control and systems engineering. The scope of the Journal will be wide and cover all aspects of the discipline including methodologies, techniques and applications. Research in control and systems engineering is necessary to develop new concepts and tools which enhance our understanding and improve our ability to design and implement high performance control systems. Submitted papers should stress the practical motivations and relevance of their results. The design and implementation of a successful control system requires the use of a range of techniques: Modelling Robustness Analysis Identification Optimization Control Law Design Numerical analysis Fault Detection, and so on.
