Abstract：To improve the utilization rate of the regenerative energy for urban rail trains,a collaborative control op-timization method based on energy conservation is proposed.A control decision model is established,which takes the parking accuracy and punctuality as constraints and takes the longest coordination time and the most coordination times as optimization objectives.According to the running speed and displacement equations of the urban rail train,the analytical solutions of the speed and time at the switching point of the train operation conditions are obtained.Combined with the influence of the integral variable on parking accuracy and running time,the value range of the integral variable is deter-mined.The integral variable is associated with the switching point of the train operation conditions,the optimal regulation strategy of the switching point of the train operation conditions is designed,and the target speed curve is calculated.The influence rule of the maximum speed of train traction on coordination time is obtained by analyzing the influencing factors of the overlapping time of the urban rail train traction and braking conditions.The collaborative control strategy is de-signed to solve the second traction time of the train and the corresponding maximum speed of the first traction.Finally,the effectiveness of the model was verified by designing an example against the background of a certain subway line in China.
