摘　　要：防抱制动系统(ABS)仿真的目的是建立汽车动力学仿真模型,并在此模型上加载防抱制动控制器模型,以观察不同控制策略在不同工况条件下的控制效果。采用解析法建立的十一自由度汽车转弯制动数学模型,并用MATLAB/SIMULINK建立仿真模型。用PID控制器对防抱制动系统的制动过程进行了仿真分析,针对PID控制器抗干扰能力不强的缺点,设计了抗干扰能力更强的模糊控制器,对仿真结果进行了对比分析。仿真结果表明模糊控制器在理想工况条件下控制效果不如PID控制器,但抗干扰能力更强。本实验为进一步硬件在线实时仿真做好准备。The simulation of Anti - Lock Brake system（ABS） is to build vehicle dynamics simulation model and load in Anti - Lock Brake controller model to observe the difference of different control strategies in different conditions. This paper adopts 11 DOF vehicle Swerve brake math model built through analysis, and builds the simulation model by MATLAB/SIMULINK. It simulates the brake process of ABS using PID controller. Considering the PID controller＇s deficiency, it designs a fuzzy controller for high noise conditions and analyses the result. The result shows that the fuzzy controller is not as good as PID controller in favorable conditions but is more robust to disturbance.. The simulation is ready for HARDWARE - IN - LOOP real - time simulation.
