Observer-based Sensor Fault Detectability : About Robust Positive Invariance Approach and Residual Sensitivity ⋆

Abstract

This paper considers detectability of deviation of sensors from their nominal behavior for a class of linear time-invariant discrete-time systems in the presence of bounded additive uncertainties. Detectable sensor faults using interval observers are analyzed considering two distinct approaches: invariant-sets and classical fault-sensitivity method. It can… (More)
