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 H_infin linear parameter varying (LPV) method that uses the fault information as one of the scheduling variables.
