摘要
为了控制轨道车辆车体的垂向振动,设计了一种参数自适应PID控制器,该控制器通过在线更新可变轨道输入参数,从而提高乘客的舒适度。正弦波轨道垂直失准和实测轨道不平顺是系统的两种不同破坏效应。通过二系悬挂对系统进行振动主动控制。以曼彻斯特基准动力学参数为基础,采用五自由度四分之一轨道车辆模型研究了轨道车辆主动悬架的应用。利用Matlab的遗传算法工具箱对自适应控制器的新参数进行了优化,在最大城市运输速度(90 km/h)下,对轨道车辆进行了模拟,以测试控制器的鲁棒性,轨道车体质量不确定度为±5%。结果表明,参数自适应PID控制器在时域和频域都具有良好的性能。
In order to control the vertical vibration of rail vehicle body,a parameter adaptive PID controller was designed to improve the comfort of passengers by updating the variable track input parameters online.The vertical deviation of sinusoidal wave orbit and the measured irregularity of orbit are two different destructive effects of the system.The active vibration control of the system is carried out by the two⁃series suspension.Based on the Manchester reference dynamic parameters,the application of the active suspension of railway vehicle was studied by using the 5-DOF quarter rail vehicle model.The new parameters of the adaptive controller are optimized by using genetic algorithm toolbox of Matlab.At the maximum urban transport speed(90 km/h),the rail vehicle simulation was carried out to test the robustness of the controller,and the load variation of the rail vehicle body was±5%.The results show that the parameter adaptive PID controller has good performance in both time domain and frequency domain.
