Abstract

This paper focuses on the derivation of a Fault Detection and Identifcation (FDI) flter for the detection of the faults that might occur during the operation of the actuator built in the suspension system. The design of the proposed FDI flter is based on dynamic inversion and on a Linear Parameter Varying (LPV) observer design. To improve the performance properties of heavy vehicles, i.e. to reduce the risk of rollovers, improve passenger comfort and road holding, a reconfgurable fault-tolerant control design of the active suspensions and the active brake is performed. However when a fault (loss in efectiveness) occurs at one of the suspension actuators a further reconfguration is needed in order to maintain the same performance level. The proposed reconfguration scheme is based on an LPV method that uses the fault information as one of the scheduling variables. The LPV based control design and the operation of the control mechanism are demonstrated through a vehicle maneuver.
