摘要：The design of State-Feedback Fault Tolerant control for Semi-Active Suspension Systems is considered in this work, that exploits diverse simple-to-implement approaches. The suspension damper is assumed to undergo multiplicative (time-varying) faults, that can be estimated by (four) modular fault estimation observers. With these fault estimations, active fault tolerant control(FTC)schemes can be synthesized, based on the reconfiguration of nominal State-Feedback policies. Seven approaches are discussed:i)Direct fault compensation;ii)Pole placement compensation; iii)Fault-dependent pole placement;iv)Linear-fault-dependent Linear Quadratic Regulator(LQR)design;v)Polynomially-fault-dependentLQRparameters;vi) LQRwith Fault-dependent controlled outputs;vii)Heuristic (vehicle-oriented) fault-dependentLQRsynthesis. The performances of these methods are analysed and compared through realistic and high-fidelity simulations. Results show the overall good operation of the latter approaches to compensate fault events and maintain performances.
