Abstract

The invention discloses a high-speed train optimized operation control method based on self-adaptive dynamic programming, a multi-mass-point coupling motion model of a high-speed train is established, and the influence rule of coupling coupler force on operation of adjacent vehicles is mainly clarified. Meanwhile, a particle swarm optimization algorithm with global optimization capacity is used for identifying dynamic parameters of running resistance and a coupler buffer device in the model in real time, and four indexes of tracking precision, running punctuality, running stability and running energy conservation of the train form constraint variables according to dispersion characteristics of power or braking force of the established train model, and the weight of the decision variable is adaptively adjusted according to the train operation state and the operation target, and the generalized tracking error value is re-inputted into the designed decentralized robust adaptive controller under the constraint of the optimization target function to obtain the control force output so as to realize the optimized and efficient operation of the high-speed train.

Description

Technical field [0001] The present invention relates to a high-speed train operation optimization control and automatic driving technology, and particularly relates to a high-speed train Optimization of Adaptive Dynamic Programming operation control method. Background technique [0002] Currently, the high-speed train operation control system as one of the main factors restricting the development of high-speed trains, most still rely on imports, its core algorithm is not fully achieved domestically, in addition, now runs high-speed trains still rely mainly on the operation of the driver, occur due to different driving situations affecting the efficiency of the driver's driving experience, but also to the driver increases the actual labor intensity. Therefore, the operation control algorithm to explore aspects of the autopilot and optimization of high-speed trains, on the one hand can effectively reduce driver workload, effectively ensure the consistency of the locomotive interval...
