Finite-time fault-tolerant control for an active suspension system

In this paper, a novel finite-time fault-tolerant control law is developed to solve the stabilization control problem of an active suspension system. The requirement of prior information about the bounds of the system uncertainties and actuator faults is obviated using the parameter adaptation laws introduced in the control scheme. Furthermore, Lyapunov's stability analysis indicates that the proposed control technique can provide desirable features such as fault-tolerant capability, finite-time convergence, robustness to model uncertainties and disturbance rejection ability. Finally, the simulation comparisons between the developed control technique and the other existing controller in the literature show the improved performance of the proposed control method regarding the ride comfort and the vehicle safety.
