In order to enhance the experience of passengers in the automatic driving track train and ensure the safe operation of the automatic driving track train,an energy-saving control technology for the traction motor of the automatic driving track train considering comfort is proposed.The kinematics model of the automatic train is built,and the energy consumption of traction and braking motors is analyzed.Based on the analysis results,the energy saving control objective function of the train traction motor is established,and the constraints are set according to the driving speed,comfort,punctuality and accurate parking.Chaos algorithm and leapfrog algorithm are used to improve the standard differential evolution algorithm to solve the objective function,obtain the optimal solution,and realize the energy-saving control of the traction motor of the automatic driving rail train.The experimental results show that the proposed method performs better in the expected speed tracking performance,energy conservation,comfort,accurate parking and punctuality,and verify that the automatic driving rail train under the application of the proposed method achieves better energy-saving control effect of traction motor on the basis of meeting the passenger comfort requirements.
