Fault Detection Based on Instantaneous Power Computation of Residue Application To Dynamical Systems

摘要

This article presents a robust strategy for sensor fault detection. This original approach is based on instantaneous power computation. An observer is used to estimate the output of the system and eliminate the unknown noise and external disturbance. The main contribution consists in developing an original strategy of fault detection based on instantaneous power calculation (FDIPC). The estimation procedure is proposed to detect potential sensor faults in linear hybrid systems. The effectiveness of the proposed approach is illustrated by numerical simulation examples. The simulation calculation was carried out using MATLAB-SIMULINK package and results have proven the excellent performance and have verified the validity and effectiveness of this approach in dynamic system.
