| 摘 要： | 一般列车自动运行(ATO)控制算法不直接考虑列车自动防护系统(ATP)限速的约束,因此可能造成列车在正常运行情况下的紧急停车。本文提出一种基于模型预测控制MPC(Model Predictive Control)的ATO控制算法,在控制器设计中直接考虑ATP限速约束,能够保证在ATO控制列车正常运行情况下不会触发ATP紧急制动,从而提高列车运行效率和舒适度。仿真结果表明该方法是有效的。

| Abstract: | Generally,the speed limits imposed by ATP(Automatic Train Protection system) are not explicitly considered in developing the ATO(Automatic Train Operation system) algorithm.This may result in emergency stops under normal train running conditions.In this paper we propose a novel ATO control algorithm based on the model-based predictive control(MPC) theory.The ATP speed limits are directly encoded as constraints in formulating the MPC design,which guarantees the speed constraints will not be violated during normal running of a train.With this control method,unnecessary emergent stops will be avoided,and the riding quality will be improved.The effectiveness of the method has been demonstrated in simulation. |
