| Abstract: | Aimed at the particularity of anti-lock braking system with road conditions changing so frequently,the self-optimizing control strategy is used.The anti-lock braking system and dynamic model are built.The self-optimizing controller is designed.It adjusts braking torques according to sign changes of variations in braking torques and adhesive torques.Simulation results verify that the self-optimizing control can search the optimal sliding rate automatically,make the system operate around sliding rate and therefore the braking effect is the best.This paper provides an effective anti-lock braking control strategy for studying vehicle braking performances. |
