An Observer-based Fault Detection Approach for Vehicle Lateral Dynamics Control System

摘要

: In this paper, an FD scheme for detecting sensor faults in Lateral dynamics system ispresented. The main contribution is to present an analytical solution to design residual generatorusing parity space approach in order to handle the time varying parameter in the system.The designed residual generator is realized in an observer structure which provides numericalstability by on-line realization. This proposed scheme can be applied for both continues anddiscrete systems. The results were implemented in Matlab/Simulink and tested with CarMakersoftware as realistic vehicle simulator
