摘　　要：以汽车起重机制动时方向稳定性及其ABS为研究对象,分析了汽车起重机急速刹车时发生甩尾的原因,利用Matlab/Simulink软件建立了ABS的仿真模型,设计了针对ABS的自适应模糊控制器,提出了基于滑移率为控制参数的模糊自适应控制策略,对汽车起重机ABS模糊控制进行了计算机模拟仿真实验。仿真结果表明:自适应模糊控制ABS能自动调节制动力,在防止车轮抱死和减小制动距离方面有明显的作用;滞后时间和制动初始速度等因素对气压ABS效果有影响。可供汽车起重机ABS进一步研发参考。This paper makes researches on the braking stability in direction and ABS of truck cranes,analyzes the reason that the behind wheels of truck cranes slide aside when qickly braking,utilizing Matlab/Simulink computer software establishes ABS simulation model,designs adaptive fuzzy controller for ABS,proposes adaptive fuzzy control strategy based on a sliding rate for the control parameter,makes computer simulation experiment on fuzzy control of truck crane ABS. The simulation result shows：that the adaptive fuzzy control ABS can automatically adjust braking force, has evident effect on preventing wheels locked and reducing braking dis- tance ; that the factors of sluggish time and braking initial velocity have influence to results of ABS. The results can be used for reference of further research and exploiting of truck crane ABS.
