Abstract

High performance control with guaranteed safety and reliability for braking systems is a challenging task due to the high nonlinearity and system uncertainties. This Paper developed a diagnosis integrated fault-tolerant control (FTC) strategy for the braking system. In fault free case the nominal controller is in operation for achieving the best performance. If fault occurs, the controller will be automatically reconfigured based on the fault information provided by the diagnosis system. The model is a time-based simulation of an anti-lock braking system (ABS) under hard braking conditions. The system fault is modeled as the uncertainty of system and can be tolerated by parameter adaption. All parameters coupled with the faulty measurement are replaced by its approximation. The tracking performance of the controlled system is guaranteed and the considered faults tolerated.
