最优速度跟踪控制策略在地铁ATO系统中的应用研究

Application of optimal speed tracking control strategy in metro ATO

精准度是列车自动运行系统(ATO)的重要性能指标,文章提出地铁列车ATO系统中的一种高精度速度跟踪控制策略,通过PID控制器参数调整、增加死区控制和附加扰动控制,实现速度跟踪精准度的优化调整。经过项目的反复验证和数据分析,充分证实此控制策略可以极大提高ATO控制的精准度,同时对地铁列车的服务质量有进一步改善。

Accuracy is essential to automatic train operation systems(ATO).This paper proposes a high-precision speed tracking control strategy in metro train ATO systems,which realizes the optimal adjustment of speed tracking accuracy by adjusting PID controller parameters,adding dead zone control and additional disturbance control.Through the repeated verification and data analysis of the project,it is fully confirmed that this control strategy can greatly improve the accuracy of ATO control,while also further improving the service quality of metro trains.
