LPV -MPC Fault Tolerant Control of Automotive Suspension Dampers

Résumé

In this short work, the problem of designing a Fault Tolerant dynamic output-feedback controller for Semi-Active Suspension Systems is considered. The suspension system is considered as subject to Loss of Effectiveness (time-varying) faults on each of the four actuators (suspension's dampers). An active reconfiguration fault tolerant scheme is proposed, considering a Linear Parameter Varying (LPV) Model Predictive Control approach. The proposed solution aims to maintain the plant's driving performances (considering handling and comfort indexes) whenever there are sudden actuator faults. These faults are identified through a parallel LPV-based FDD scheme, which is also explained. The performance of the proposed control structure is demonstrated through simulation. Results show the overall good operation of this control scheme, which is compared to other standart control approaches.
