Study of a CRONE Suspension Based on MR Semi-Active Control

The CRONE suspension, French acronym of "suspension a Comportement Robuste d'Ordre Non Entier", results from a traditional suspension system whose spring and damper are replaced by a mechanical and hydropneumatic system defined by a fractional order force-displacement transfer function. But the mechanism structure of this suspension is complex, higher consumption of energy and difficult to be realized. On the other hand, the MR semi-active control strategy is easy to realize. In this paper, therefore, a new CRONE suspension with MR semi-active control is built combining the advantages of MR technique and the CRONE suspension. The simulation results indicate that the performances of suspension could be improved and this new semi-active control strategy is validity.
