摘要

本文研究了轨道车辆半主动悬架的建模与控制。建立了带乘客座椅的四分之一轨道车辆半主动和被动悬架的垂直运动分析模型。为了提高乘客的舒适性，设计了PID-ZN和LQR两个控制器。这种舒适性是根据乘客位移和振动来评估的。这些舒适性标准被评估为轨道缺陷激励的响应。结果表明，与PID控制器相比，采用LQR控制器的半主动悬架产生了最好的结果。

Control and vibration of rail vehicle semi-active suspensions with comfort evaluation

This paper deals with the modelling and control of rail vehicle semi-active suspensions. The analytical models of the quarter rail vehicle with a passenger seat, describing the vertical motion, are presented for semi-active and passive suspensions. Two controllers, i.e., PID-ZN and LQR are designed in order to improve the passenger comfort. This comfort is evaluated in terms of the passenger displacement and vibration. These comfort criteria are evaluated as a response of a rail imperfection excitation. The obtained results prove that the semi-active suspension with a LQR controller yields the best results compared to PID controller.
