摘　　要：针对传统PID控制在高速列车智能控制方面对环境干扰等因素过于敏感,结合模糊控制方法,提出基于模糊自适应PID控制的高速列车悬挂系统智能控制算法,搭建了17自由度半主动悬挂横向动力学模型,建立以阻尼系数作为控制器输出变量的模糊自适应PID控制策略,在MATLAB/Simulink模块中搭建列车悬架仿真模型。仿真结果表明:基于模糊自适应PID控制的半主动悬挂减振效果要明显好于传统PID控制算法下的悬挂系统,车辆行驶平稳性和乘客乘坐舒适度都有了显著提高。Traditional PID control is too sensitive to environmental interference and other factors in intelligent control of High-speed trains.Combined with fuzzy control methods,the intelligent control algorithm of high-speed train suspension system based on fuzzy adaptive PID control is proposed,a 17-degree-of-freedom semi-active suspension lateral dynamics model is constructed,the fuzzy adaptive PID control strategy with damping coefficient as the output variable of the controller is established,and the simulation model is constructed under MATLAB/Simulink environment.The simulation results show that the semi-active suspension dampening effect based on fuzzy adaptive PID control is significantly better than that of the suspension system under the traditional PID control algorithm,and the smoothness of the vehicle and the comfort of the passenger’s ride have improved significantly.
