摘要

本文研究了有耗通信网络上的连续状态观测问题。我们考虑用于测量设备输出的采样器是空间分布的,并且它们与观测器的通信是根据轮循调度协议进行调度的情况。我们允许观测器增益与通信调度同步动态变化。在此背景下,我们提出了一个线性矩阵不等式(LMI)框架来设计观测器增益,以确保误差动力学在连续时间内的渐近稳定性。我们通过几个数值模拟来说明所提出方法的有效性。

Design of Gain Switching State Observer with Signal Losses
In this paper, we study the problem of continuous-time state observation over lossy communication networks. We consider the situation in which the samplers for measuring the output of the plant are spatially distributed and their communication with the observer is scheduled according to a round-robin scheduling protocol. We allow the observer gains to dynamically change in synchronization with the scheduling of communications. In this context, we propose a linear matrix inequality (LMI) framework to design the observer gains that ensure the asymptotic stability of the error dynamics in continuous time. We illustrate the effectiveness of the proposed methods by several numerical simulations.
