Abstract: Longitudinal wheel slip control is a crucial problem in automotive systems, as it it is the basis for traction, braking and stability control. Slip dynamics get faster, and thus more difficult to govern for the rider, as speed decreases: hence, at low speed one would willingly lose tracking performance in exchange for increased safety. To achieve this, we propose a novel Switched Second Order Sliding Mode (S-SOSM) control strategy, which allows enhancing the closed-loop performance and to tune them to the current working condition. The validity of the approach is on traction control of two-wheeled vehicles.
Keywords: second order SMC; sliding mode control; switched systems; wheel slip control; automotive systems; two-wheeled vehicles; slip dynamics; traction control.
