摘　　要：为了能够获得较好的制动控制效果,解决不同路况下因滑移率不同而产生的系统误差问题,提出了基于模糊免疫PID的汽车防抱死控制策略。根据汽车防抱死动力学方程,利用simulink搭建了其仿真模型,并设计了模糊免疫PID控制器。仿真结果表明:与传统的PID控制算法相比,模糊免疫PID控制在混凝土、湿沥青和湿泥土路面上,制动时间、制动距离和达到最佳滑移率时间等参数都有明显的减小,证明了该算法的有效性。In order to obtain better braking control effect and solve the system error problem caused by different optimal slip ratio under different road conditions,the anti-lock control strategy based on fuzzy immune PID is proposed.Firstly,according to the anti-lock dynamic equation,the simulation model is built by Simulink.What’s more,the fuzzy immune PID controller is designed.The simulation results show that compared with the traditional PID control algorithm,the fuzzy immune PID control on the concrete,wet asphalt and wet soil road,the parameters such as braking time,braking distance and the time to achieve the best slip rate are significantly reduced,which proves the effectiveness of the proposed algorithm.
