An Onboard Optimal Control System for Freight Trains

This thesis aims to probe into optimal control approaches for freight train by giving priority to the objective of minimizing energy consumption, which is also expected to design the algorithm for optimal real-time control of freight train based on the handle control of the locomotive, and develop a set of guiding devices applicable to optimal control of train under different signal systems and railway conditions. The guiding devices is capable of conducting dynamic collection of train running information to proceed with the online design of guiding proposal for optimal control applicable to the current running environment. According to the results of test carried out at the section between Changanji-Dagudian under the governance of Shanghai Railway Administration, the guiding devices can reduce the energy consumption and delays while ensuring the safe and smooth running.
