Robust and rapid control for ABS based on global sliding mode

To satisfy the stability and anti-jamming performance, robust theory must be adopted in the design for Antilock Braking System (ABS) controller. In this paper, the nonlinear and time-varying mathematical model of the antilock braking system (ABS) is established, the global sliding mode controller is designed based on slip-ratio, which make the system State always lies on the sliding surface, and the robustness of sliding mode control system can be improved to some extent. The Simulation results on different surfaces prove that this strategy is feasible and effective, which can shorten the braking distance and the braking time.
