Adaptive fault tolerant control for active suspension

Abstract

This paper deals an adaptive fault tolerant control for active suspension in the presence of actuator saturation. An adaptive state-feedback controller is designed to tackle the issue of actuator fault. A Disturbance observer is utilized to observe the lumped disturbance. The partial actuator fault or actuator inefficiency is consider as an actuator fault. The fault is estimated and then compensated by the use of adaptive state feedback control law. The proposed controller is verified by the simulation.
