This paper presents a parameter-adaptation sliding control algorithm based on the analysis of zero-order switching sliding mode control algorithm for the non-linear control model of Antilock-Braking System (ABS). The algorithm, which combines sliding mode control, adaptive control and ABS, weakens the influence of chattering on braking process. The closed loop emulated system of ABS, on which ideal and half practical simulation are completed, is designed and constructed. The results of simulation verify that the adaptive sliding algorithm has the advantage of less the brake torque chattering and smoothening fluctuation of wheel speed signals compared with pure sliding control algorithm.
