The invention provides a scene self-adaptive rail transit ATO (automatic train operation) control system which comprises an operation information acquisition module 201, a scene self-adaptive control module 202 and a train traction/brake execution module 203. The scene self-adaptive control module 202 receives information input of the operation information acquisition module 201; and a control instruction is formed through learning, prediction and optimization and is input to the train traction/braking execution module 203. In the system, the parameter setting module carries out self-setting on five controller parameters of the sliding mode PID controller, compared with manual parameter setting, the efficiency and precision are higher, and more controller parameter setting time during train pilot run is saved; the system prediction module can effectively restrain the situation that excessive overshoot is likely to be generated when the working conditions of the train are switched, emergency braking triggered by the fact that the overshoot exceeds the maximum overshoot threshold value in the running process of the train is avoided, and meanwhile the accuracy of a train ATO controller for tracking a target curve is improved.
本发明提出一种场景自适应的轨道交通ATO控制系统,包括运行信息获取模块201、场景自适应控制模块202和列车牵引/制动执行模块203,所述场景自适应控制模块202接收运行信息获取模块201的信息输入,通过学习、预测和优化后形成控制指令输入给所述列车牵引/制动执行模块203。本发明系统中,参数整定模块对滑模PID控制器的五个控制器参数进行自整定,与手动参数整定相比具有更高的效率和精度并节省了更多列车试运行时控制器参数整定的时间;系统预测模块可以有效抑制列车在工况发生切换时容易产生过量超调的情况,避免了列车在运行过程中因超调量超过最大超调阈值触发的紧急制动,同时提高了列车ATO控制器跟踪目标曲线的精度。
