Train control method and device based on maglev train control system and controller

Abstract

The invention provides a train control method and device based on a maglev train control system and a controller. The controller obtains set physical parameters of a maglev system, gap data between a track and a train body and a pre-established control signal model; wherein the gap data is acquired through a gap sensor; the control signal model is established by constructing a nonlinear dynamic model of a suspension frame based on a suspension mechanism of the magnetically levitated train and introducing a disturbance signal; inputting the physical parameters and the gap data of the magnetic suspension system into a control signal model to output a control signal; and finally, the control signal drives the suspension electromagnet to move to a target position through the chopper. According to the train control method in the embodiment of the invention, disturbance is considered, and the control energy consumption can be greatly reduced by utilizing the positive effect of the disturbance; and the anti-interference capability is high. 本申请提供了一种基于磁悬浮列车控制系统的列车控制方法、装置和控制器，控制器获取设定的磁悬浮系统物理参数、轨道与车体间的间隙数据和预先建立的控制信号模型；其中，间隙数据是通过间隙传感器采集的；控制信号模型是基于磁悬浮列车的悬浮机制构建悬浮架的非线性动力学模型，并引入扰动信号而建立的；然后将磁悬浮系统物理参数和间隙数据输入至控制信号模型，以输出控制信号；最后将控制信号通过斩波器驱动悬浮电磁铁移动到目标位置。本申请实施例中的列车控制方法，考虑了扰动，并利用扰动的积极效应能够极大减少控制耗能；并且抗干扰能力强。
