Energy-saving automatic optimisation of train speed commands using direct search techniques

Abstract

This paper describes two computer tools that have been developed for the automatic optimisation of train speed commands. Given a target time for the trip between two consecutive stations, energy consumption is minimised. Two driving strategies have been considered, one based on coasting-remotor cycles and the other in space-related traction commands. Direct search techniques have been applied, using simulation processes that include detailed models of the train and the line.This paper describes two computer tools that have been developed for the automatic optimisation of train speed commands.
