A Gain-Scheduling Control Method for Automotive Vehicle Stabilization

In this paper, a gain-scheduling controller for automotive vehicles is proposed. This controller is to protect the vehicle from spin and realize the improved cornering performance. Since the vehicle unstabilization is mainly caused by the cornering force saturation of rear tire. This saturation is considered explicity in design by using LPV modelling method. And a gain-scheduling controller is designed based on linear matrix inequality (LMI) approach. Simulation shows that the vehicle stability performance is improved significantly as compared with robust control based on linearized model.
