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
