A Self Tuning Suspension Controller for Multi-body Quarter Vehicle Model

International audienceIn this paper we derive both LTI (Linear Time Invariant) and LPV (Linear Parameter Varying) controllers according to the Hinf methodology, based on a simple two degree-of-freedom quarter vehicle model using an industrial criterion to handle the compromise between comfort and suspension deflection. As such a model is very simplified, a validation of these control designs is performed on a multi-body dynamical model of the quarter vehicle, much closer to a realistic car which makes the solution interesting for implementation issues
