Abstract

In this article, we study a Networked Control System (NCS) with multiplexed communication and Bernoulli packet drops. Multiplexed communication refers to the constraint that transmission of a control signal and an observation signal cannot occur simultaneously due to the limited bandwidth. First, we propose an ε-greedy algorithm for the selection of the communication sequence that also ensures Mean Square Stability (MSS). We formulate the system as a Markovian Jump Linear System (MJLS) and provide the necessary conditions for MSS in terms of Linear Matrix Inequalities (LMIs) that need to be satisfied for three corner cases. We prove that the system is MSS for any convex combination of these three corner cases. We validate our approach with a numerical example that shows the effectiveness of our method.

基于贪心通信选择算法的多路NCS稳定性研究

本文研究了具有多路通信和伯努利丢包的网络控制系统（NCS）。多路通信是指由于带宽有限，控制信号和观测信号不能同时传输的约束。首先，我们提出了一种ε-贪婪算法来选择通信序列，同时保证均方稳定性（MSS）。我们将该系统表述为一个马尔可夫跳变线性系统（MJLS），并从三种极端情况下需要满足的线性矩阵不等式（lmi）的角度给出了MJLS的必要条件。我们证明了对于这三种情况的任意凸组合，系统都是MSS。通过一个数值算例验证了该方法的有效性。

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.
