高速列车座椅主动悬架的模糊控制与PID控制系统
|
摘要
建立了基于主动悬架的的高速列车悬架—座椅—人体的四自由度动力学模型,并对该列车模型平顺性的优化控制进行了研究。针对该座椅主动悬架模型设计了模糊控制器、传统PID控制器与自适应的模糊PID控制器,应用Matlab/Simulink软件在相同的工况下进行仿真实验,并将三种控制方法下的仿真结果与被动悬架车辆模型的仿真结果进行对比分析。结果表明,相较与被动悬架车辆模型,上述三种控制方法下的主动模型座椅处的振动特性都得到了改善,达到了预期的控制效果,且自适应模糊PID控制下的改善程度最佳,对高速列车乘坐舒适性的提高有着一定的理论参考意义。
A four-degree-freedom dynamic model of a suspension-seat-person high-speed train is established, and the optimization control of ride comfort of the vehicle model is also studied. By using fuzzy control, traditional PID control and adaptive fuzzy PID control method, the active suspension is designed and simulated in Matlab/Simulink under the same condition. The comfort and operational stability of passive suspension, active fuzzy control, PID control and adaptive fuzzy PID control are compared and analyzed. The experimental results show the above three control methods have greatly improved the performance of passive seat suspension, achieved the desired control effect, and the adaptive fuzzy PID control is better than the previous two. It has a certain theoretical reference value for improving the riding comfort of high-speed trains.
