Problems solved by technology

[0004] Using model predictive control to study the cooperative operation of formation trains is often only focused on how to form a formation, that is, how to make multiple vehicles reach the state of speed convergence, and the control target finally maintains a stable speed, which leads to consideration of speed, distance, comfort, etc. in the optimization control. When multi-objective, fixed weight coefficients are often used, making it difficult to deal with the trade-off problem of multi-objective optimization under complex working conditions in actual engineering

Abstract

The embodiment of the invention provides a formation operation control method and device for trains and a storage medium, and the method comprises the steps: determining the operation condition information of a train formation formed by a plurality of trains according to the operation state information of the trains; acquiring running state deviation information between adjacent trains in the train formation; according to the operation condition information and the operation state deviation information, weight coefficients corresponding to multiple target physical quantities of the train formation are optimized and adjusted; determining an expected value corresponding to each target physical quantity according to the weight coefficients corresponding to the optimized and adjusted target physical quantities; and controlling operation of each train in the train formation according to the expected value corresponding to each target physical quantity.

Description

technical field [0001] The present application relates to the technical field of train operation control, for example, to a train formation operation control method, device and storage medium. Background technique [0002] Train formation operation refers to the communication between trains and trains. Through advanced control means, the trains and trains can form a speed convergence, maintain a short distance and cooperate to run, forming a virtual connected state. In order to flexibly complete multi-scenario tasks such as efficient dynamic formation and unmarshalling and smooth coordinated formation operation according to operational requirements, an existing distributed-based virtual formation operation control method for subway trains includes: S31: Establish dynamic operation of subway trains Model; S32: Design predictive control algorithm, set predictive control time domain, within the set predictive control time domain, according to the dynamic operation model of subw...
