Abstract
An algorithm optimizing the train running profile with Bellman’s Dynamic
programming (DP) is investigated in this paper. An optimal train running
trajectory which minimizes amount of total consumed energy has been produced
under fixed origin and destination, stipulated running time, limited electric
motive force and electric brake by VVVF controlled induction motor/generator
blended with mechanical brake, several local speed constraints and local inclines.
Many previous works on this area adopt the numerical techniques of calculus of
variations, Pontryagin’s maximum principle, incremental method, and so on. But
these methods often meet some difficulties accounting for complicated actual
train running preconditions, e.g. complicated functions which describe electrical
motive/brake torque, local constraints o
