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。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 emer- gency 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 con- straints in formulating the MPC design, which guarantees the speed constraints will not be violated during nor- mal 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.
