摘要
针对汽车防抱死制动系统中路况经常变化的特殊性,提出了将自寻最优控制策略应用到防抱死控制中.构建了防抱死制动系统和制动时车辆动力学模型,设计了依据制动力矩和附着力矩变化量符号改变来调节制动力矩的自寻最优控制器.仿真结果验证,自寻最优控制可以自动搜寻到最佳滑移率,并使系统在最佳滑移率附近工作,达到最佳制动效果.本文为汽车制动性能的研究提供了有效可行的防抱死控制策略.
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.
