A LPV traction control approach for independent in-wheel electric motor vehicle

Abstract

This paper presents a traction control strategy via LPV(Linear Parameter Variable) slip ratio control method for independent in-wheel motor electric vehicle. In order to simplify the controller design and implement distributed control system in each wheel, the slip ratio control model with LPV form and uncertain disturbance is derived. Furthermore, a two-degree-of-freedom LPV controller with disturbance rejection is designed. The key of traction control is to ensure the slip ratio within the limitation region, so we address a traction control strategy to limit slip ratio for each wheel by slip ratio control. The simulation results show the effectiveness of the traction control strategy and the slip ratio controller proposed in this paper.
