摘要

本文研究了有限记忆观测器(FMO)设计在多面体模型中的应用。在对线性系统的FMO作了简单的介绍之后,然后考虑了用Takagi-Sugeno (T-S)或Poly-topic形式表示的非线性模型。将考虑观测器设计应用于未知输入的非线性离散系统的故障诊断,其中提出了联合系统状态和未知输入估计。

Finite memory state observer design for polytopic systems. Application to actuator fault diagnosis
This paper addresses the Finite Memory Observer (FMO) design applied to polytopic models. After a brief introduction on FMO for linear systems, the nonlinear models represented in a Takagi-Sugeno (T-S) or Poly-topic form are then considered. The considered observer design will be applied to investigate the fault diagnosis for nonlinear discrete-time systems subject to unknown input where joint system states and unknown inputs estimation is proposed.
