Abstract :
To improve the performance properties of heavy vehicles, i.e. to reduce the risk of emergencies, improve passenger comfort and road holding, a reconfigurable fault-tolerant control design of the active suspension is performed. When a fault (loss in effectiveness) occurs at one of the suspension actuators a reconfiguration is needed in order to maintain the same performance level. The proposed reconfiguration scheme is based on an Hinfin linear parameter varying (LPV) method that uses the fault information as one of the scheduling variables.
