摘要

研究了用于故障检测的连续多变量线性系统的函数区间观测器设计问题。首先，推导了一组存在条件，并给出了建立类luenberger区间观测器的简单过程。然后，利用残差信号的区间估计，提出了一种FD方法。最后，通过数值算例验证了所提方法的正确性和有效性。

Functional Interval-Observer-Based Fault Detection for Continuous-time Multivariable Linear Systems

This paper deals with the problem of the functional interval observer design for continuous-time multivariable linear system applied to fault detection purpose. First, a set of existance conditions is deduced as well as a simple process to built the Luenberger-like interval observer. Then, by utilizing the interval estimation of residual signals a FD procedure is developed. Finally, the validity and the effectiveness of the suggested method is verified by a numerical example.
