Adaptive Fault Tolerant Controller for Nonlinear Active Suspension.

In this paper, the fault tolerant control problem of nonlinear active suspension is concerned. A RBF-based SMC fault tolerant controller is developed to improve the ride comfort and handling stability under partial loss of actuator effectiveness fault. At first, a quarter car nonlinear active suspension model and fault model are established. Next a RBF-based SMC adaptive controller is conducted for the faulty suspension system. Simulation is provided and simulation results show that the proposed method can effectively compensate for faults and improve the ride comfort. Then the proposed controller is verified by the simulation.
