Passive fault tolerant control design of energy management system for electric vehicle

In this paper, we present a passive fault tolerant control energy management for two-converters parallel configuration in electrical vehicle system. The passive FTC is based on H-infinity approach (H-infinity full order and fixed H-infinity structure); this PFTC is coupled with the optimal control to optimize the consumption of the FC fuel. This architecture is proposed to ensure the stability with an acceptable performance of the system in the faulty mode. To test this architecture, we introduce a fault in the DC bus voltage sensor, and we compare the behavior of the system in the case of a PI controller and robust fault tolerant controller. The simulation results proved the effectiveness of the H-infinity FTC synthesis and the two kinds of H-infinity synthesis are discussed.
