A multi-modes semi-active suspension control strategy for Peugeot 308 RCZ vehicle

In this paper, a new semi-active suspension control strategy is proposed for the Peugeot 308 RCZ vehicle. The aim of this study is to automate transition between the two modes of suspension based on nonlinear damping laws and using a variable damper. By minimizing a quadratic gap between a control target and the control actuation force issued from each mode, a decision strategy is defined and a suspension mode is selected, so that the variable damper can achieve it by controlling the actuation force. The used control target is synthesized using CRONE-SkyHook approach. Simulation results show that the requirements in terms of passenger comfort and vehicle stability are reached applying the proposed control strategy.
