Discussion on: 'Robust Fault Detection Observer and Fault Estimation Filter Design for LTI Systems Based On GKYP Lemma'

摘要

Many practical dynamics systems are subject to various environmental changes, unknown disturbances, and changing operating conditions, thus faults in those systems are inevitable. Therefore, fault detection and isolation have attracted considerable attention over the decades. In observer-based fault detection design, a basic objective is to reduce the effect of disturbances to residual signals and to enhance the influence of faults to residuals.
