  • To ensure energy-saving and punctual operation of urban railway, a time-approaching search method was proposed. The energy-saving control model of urban railway that satisfies timing running was established . A set of optimal conditions for energy-saving control was derived according to the Pontryagin maximum principle. The energy consumption of a train under different energy-saving operations was calculated . On this basis, we presented an optimization method of dividing the train operation period into sections. The change point of train operation is determined using time-approaching search method to meet the requirements of energy-saving and timing. A section from Tieli Road to Youyi Road of Shanghai Metro Line 3 is taken as an example. Compared with measurement results in the practical loading process, the energy comsuption is reduced by 12.5% using time-approaching search algorithm.
