摘要

本文旨在为测量延迟和数据包丢失的多速率采样系统开发后退视界(RH)估计。文章引入了一种事件触发传输方案,以去除对估计器设计不必要的测量。引入随机对角矩阵来表示丢包现象,其中每个分量都受制于一个单独的伯努利过程。首先利用重组观测法将原始系统转换为无延迟系统。然后,基于新系统,通过最小化包含一些终端加权项的给定成本函数,提出了批量形式和迭代形式的 RH 估计。通过自然假设保证了所提出的相对湿度估计的稳定性,并给出了一个仿真实例来验证所提方法的有效性。

Receding horizon estimation for multi-rate sampled data systems under component-based event-triggered mechanisms: Handling delayed and degraded measurements

The purpose of this article is to develop the receding horizon (RH) estimation for multi-rate sampled systems with measurement delays and packet losses in the measurements. An event-triggered transmission scheme is introduced to remove measurements that are unnecessary for the design of the estimator. The stochastic diagonal matrixes are introduced to represent the phenomenon of packet losses, where each component is subject to an individual Bernoulli process. The original system is firstly transformed into a delay-free one by using the reorganized observation method. Further, a batch form and an iterative form of RH estimation are proposed by minimizing a given cost function that includes some terminal weighting terms based on the new system. The stability of the proposed RH estimation is guaranteed by the natural assumptions and a simulation instance is given to verify the effectiveness of the proposed method.

期刊介绍: IET Control Theory & Applications is devoted to control systems in the broadest sense, covering new theoretical results and the applications of new and established control methods. Among the topics of interest are system modelling, identification and simulation, the analysis and design of control systems (including computer-aided design), and practical implementation. The scope encompasses technological, economic, physiological (biomedical) and other systems, including man-machine interfaces. Most of the papers published deal with original work from industrial and government laboratories and universities, but subject reviews and tutorial expositions of current methods are welcomed. Correspondence discussing published papers is also welcomed. Applications papers need not necessarily involve new theory. Papers which describe new realisations of established methods, or control techniques applied in a novel situation, or practical studies which compare various designs, would be of interest. Of particular value are theoretical papers which discuss the applicability of new work or applications which engender new theoretical applications.
