Abstract :
In this paper actuator fault diagnosis problem in active vehicle suspension system is investigated. Full car model is used in the study. A fault diagnosis approach based on Unknown input observer (UIO) is used for detection of actuator faults. A bank of observers is used to design a fault isolation scheme for actuator faults.
