A Modeling and Distributed Cooperative Control Method for Train System

Abstract

The invention discloses a train system modeling and distributed collaborative control method, comprising: step 1: setting trains running on the same track as research objects; Establish a dynamic model based on information characteristics; Step 3: Design and execute a corresponding distributed control algorithm according to the dynamic model to realize multi-train coordinated control. The present invention establishes a train dynamics model based on information such as the speed constraint of the train running line, train running damping (track friction, rolling resistance, track slope resistance, air resistance, etc.), so that multiple trains on the same line can achieve safety and high efficiency. It can stop on the ground, and the adjacent trains keep the desired safety distance, which can solve the multi-train cooperative control problem based on moving block and uncertain damping parameters, and has the advantages of safety and efficiency.

Description

technical field [0001] The invention relates to the field of train system operation control, in particular to a high-speed train system modeling and distributed collaborative control method with constrained speed and uncertain operation damping parameters. Background technique [0002] As a new product of the 21st century, high-speed railway has the characteristics of large carrying capacity, fast operation speed and high transportation efficiency compared with the traditional railway system. With the rapid development of my country's high-speed railway industry, people's work and life between cities have been greatly improved. In the context of the rapid development of rail transit, the improvement of high-speed railway operation efficiency has important practical significance. The traffic blocking modes of trains are mainly divided into three categories, namely fixed blocking, quasi-moving blocking and moving blocking. Among them, the fixed block divides the block area a...

Problems solved by technology

Using the mobile block method, because the distance between trains becomes shorter, it is a huge challenge for the safety of train operation, so it has not been realized on the current high-speed railway

Not only that, but the existing research does not consider the situation that the train speed is constrained and the operating damping parameters are uncertain, but these conditions exist objectively in the actual operation of the train and have an important impact on the train operation
