Fault detection using luenberger observer in a railway system

Abstract

This paper deals with the problem of diagnosis of linear system defects. The problem of fault detection under disturbances for multi-input and multi-output (MIMO) system. Fault detection can be investigated by generating residuals. These residuals can be generated using different methods. In this paper we will used one of the finest methods for generating residuals is luenberger observer (LO). Fault can be detected and isolated simply with the help of the generated residual. Where the simulation results on a railway system demonstrate that the effectiveness of the proposed approach.
