Abstract

In this paper, we will propose a solution to estimate the defect at the input of a non-linear system based on the ARX-Laguerre multimodel. So, we will present the design of the PI (Proportional Integral) observer based on the ARX-Laguerre multimodel. and the gains of which will be calculated by an algorithm for detecting and estimating input faults in non-linear systems. The detection and estimation algorithm is based on the Linear Matrix Inequality (LMI) optimization method.

基于ARX-Laguerre多模型的故障诊断
在本文中,我们将提出一种基于ARX-Laguerre多模型的非线性系统输入缺陷估计方法。因此,我们将提出基于ARX-Laguerre多模型的PI (Proportional Integral)观测器的设计。通过非线性系统输入故障的检测和估计算法来计算其增益。检测和估计算法基于线性矩阵不等式(LMI)优化方法。
