摘要

摘要本文提出了一种基于区间观测器诊断由具有外生干扰的离散时间模型描述的线性动态系统的方法。本文推导了一个区间观测器的构造公式，该观测器可产生如下两个残差值：如果零位于这两个值之间，则系统没有故障，观测器无法检测到故障。如果零值不属于这两个值之间的区间，则视为发生故障。下面通过一个例子来说明理论结果。

An Interval Observer-Based Method to Diagnose Discrete-Time Systems

This paper proposes a method for diagnosing linear dynamic systems described by discrete-time models with exogenous disturbances based on interval observers. Formulas are derived to construct an interval observer producing two values of the residual as follows: if zero is between these values, then the system has no faults to be detected by the observer. The case where zero does not belong to the interval between these values is qualified as the occurrence of a fault. The theoretical results are illustrated by an example.

期刊介绍： Automation and Remote Control is one of the first journals on control theory. The scope of the journal is control theory problems and applications. The journal publishes reviews, original articles, and short communications (deterministic, stochastic, adaptive, and robust formulations) and its applications (computer control, components and instruments, process control, social and economy control, etc.).
