The first one is based on sliding mode observers. The principle is to reconstruct the state vector and the outputs of the system by sliding mode observers and to compare the estimated outputs with those measured, the obtained difference is considered as residual. The second approach rests on nonlinear analytical redundancy (NLAR) and consists to eliminate the unknown states and variables in order to obtain relations where all variables are known. The objective of this paper is to show the interest of the two approaches for detecting sensor or actuator faults of autonomous electric vehicle. Simulation results show that the method of NLAR is more adequate to detect actuator faults and the sliding mode observer is better for detecting sensor faults.Lire moins >
