摘要：
A closed-loop cruise controller is proposed to minimise the running cost of heavy-haul trains equipped with electronically controlled pneumatic brake systems. Consideration is given to improving velocity tracking, in-train force management and energy usage. To overcome the communication constraints, a fencing concept is introduced, whereby the controller reconfigures adaptively to the current track topology. Simulation results of comparisons between different controllers are provided: open-loop versus closed-loop; velocity tracking versus in-train force. Different train control configurations are also compared: unified control, adaptive fencing and full independent traction and braking. (c) 2006 Elsevier Ltd. All rights reserved.
