摘要

The design of a Fault Tolerant dynamic output-feedback controller for Semi-Active Suspension Systems is considered in this work. The suspension system is assumed to undergoloss of effectiveness(time-varying) faults on each of the four actuators (suspension’s dampers). An active fault tolerant reconfiguration scheme is proposed, considering a Linear Parameter Varying(LPV)Model Predictive Control approach. The proposed solution aims to maintain the vehicle’s driving performances (handling and comfort indexes) whenever there are sudden actuator faults. These faults are identified through a parallel Fault Detection and Diagnosis scheme, which is also explained. The performance of the proposed control structure is demonstrated through simulation. Results show the good operation of this control scheme which is compared to other standard control approaches, considering a reduced-size car.
