Optimal Cruise Control of Heavy-Haul train equipped with Electronic Controlled Pneumatic Brake Systems
Abstract
In this paper a closed-loop cruise controller to minimise the running costs of the heavy-haul train is proposed. Consideration is given to velocity tracking, in-train force and fuel consumption, as well as optimisation of them. To overcome the communication constraints, a fencing concept is introduced whereby the controller is reconfigured adaptively to the current track topology. Simulation results on comparisons between different configurations are given: open-loop versus closed-loop; optimal velocity tracking versus optimal energy usage; and the improvement of adaptive fencing over general closed-loop control.
