Title   Harmonic analysis of metro vehicle EMC software Design
Abstract
Subway trains running velocity curve optimal control may be the reference to the design and operation of subway trains. With large transport volume, high energy consumption, subway trains need to be studied on how to save running energy. This paper has completed the following contents: studied on the velocity, energy and current curve ,and observed their relationship; proposed control strategy to optimize the velocity curve to save energy, and completed the running subway trains’modeling and simulation;finished  the program of trains running and optimal control, which generated the curve of trains' running regard to time; studied on different cases such as single and double coasting points, different capacity rate, single or multi-particle model, analyzed the results of each simulation and put forward the best control strategy; accomplished the graduation project of subway trains runing velocity curve optimal control. 源自六/维\论]文[网!加7位QQ324.9114 www.lwfree.cn
