Applicative Fault Tolerant Control for Semi-Active Suspension System : Preliminary Results

Résumé

This paper presents applicative results about fault detection and control for semi-active suspension system. The control is extended from the ''Acceleration Driven Damping'' (ADD) controller combined with a robust fault detection scheme in order to estimate the fault. The approach, based on a quarter of vehicle model includes the nonlinearities of the shock absorber. The robust fault estimation module is based on $\mathcal{H}_\infty$ background providing robustness. It aims to estimate a sensor fault on the system, especially a bias on accelerometers. Combination of both strategies allows to attenuate the effect the fault on the system. This approved structure aims to be implemented in real time. Validations has been made in a F-Class vehicle in Carsim software which provides realistic non-linear vehicle behavior. Results show the effectiveness of the fault tolerant strategy for semi-active dampers.
