Robust Yaw-moment Control for electric vehicles

Many investigations have demonstrated that the Direct Yaw-moment Control (DYC) is an effective way to enhance the reliability and safety of electric vehicles. Especially, the in-wheel motor electric vehicles, which independently equips electric motor on each propulsion wheel. This benefit endows the control system with a faster response than the internal combustion engine vehicles. In this paper, a robust DYC for rear-wheel drive in-wheel motor electric vehicles is proposed. Due to the achievement of robust control framework, the presented system can deal with model uncertainty, side wind disturbance, and parameter varying problems. The simulation results show that the presented solution not only achieves good performance on yaw-moment control, but also has good insistency against all system perturbations.
