Design of fault-detecting-observer for four-tank system

本篇论文主要针对四水箱系统、介绍了如何在simulink仿真软件中对其进行系统模型的搭建和仿真还有故障诊断设计。在Luenberger观测器的基础上变换得到适用于该模型的故障检测观测器、输出故障信息,并且能够做到故障分离。

Aim at the four-tank system,This paper introducs how to complete the model of the four-tank system and design the fault-diagnosis system of it in the software of simulink for simulation.Base on the Luenberger-observer we can get the fault-detecting-observer, which is fit for it,finding the fault-information, furthermore,we also can separate these faults.
