Active suspension control systems, which are designed by linear methods, can only serve as a trade-off between these conflicting performance criteria. Both performance objectives can only be accomplished at the same time by using a non-linear controller. This paper addresses the non-linear induced L-2 control of an active suspension system, which contains non-linear spring and damper elements. The design method is based on the linear parameter varying (LPV) model of the system. The proposed method utilizes the bilinear damping characteristic, stiffening spring characteristic when the suspension deflection approaches the structural limits, mass variations and parameter-dependent weighting filters. Simulation studies both in time and frequency domain demonstrate that the active suspension system controlled by the proposed method always guarantees an agreement between acceleration (comfort) and suspension deflection magnitudes together with a high ride performance.eninfo:eu-repo/semantics/closedAccessactive suspension systemLPV controlLPV modellingnon-linear modellingArticle311719510.1177/01423312080906302-s2.0-58349108145Q2WOS:000263421300005Q4
