摘要

建立了六自由度转向架模型, 研究转向架动力系统的时滞输出反馈控制, 通过部分可测输出量实现整个系统的振动控制。将系统的运动微分方程改写成状态空间模型, 其控制输入中存在时滞。然后, 利用一个线性项加积分项的变换将原时滞输入系统转化成无时滞的形式。在此基础上, 应用输出反馈原理和合理的性能指标函数, 以开关控制策略为依据设计了系统的时滞半主动控制律。最后, 以一个具有典型参数的转向架模型为例来阐明所提出的控制策略的应用步骤。数值结果表明:所设计的时滞半主动控制策略是有效的。

Abstract

A 6 DOF railbogie model established here was used to investigate the time delay output feedback contro of rail-bogie dynamic system.A vibration control rule for the entire system was designed in terms of the measurable output of the system.The differential equation of motion of the system was transformed to a state-space model with time delay in the control input.Then, a transformation with a linear term and an integral term was employed to transfer the original time delay system into a form without time delays.Accordingly, a time delay semi-active control rule for the system was designed based on the principle of output feedback,a reasonable performance index, and the“on-off” control strategy.Finally,a rail-bogie model with a set of typical parameters was taken as an example to illustrate the application procedure of the control strategy proposed.The numerical results show that the time delay semi-active control strategy designed here is effective.
