Embodiment Construction

[0029] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred examples and accompanying drawings. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0030] The present invention proposes a distributed train control method considering packet loss, including:

[0031] S11: collect the real-time running status of the train, and calculate the deviation between the speed of the current train and the offset of the coupler and the target speed and the offset of the coupler;

[0032] S12: Calculate the state feedback control law;

[0033] S13: According to the state feedback control law and the state deviation, calculate the control force u for each car k ;

[0034] S14: Set the control force u k applied to each car;

[0035] S15: Determine whethe...

Abstract

The invention relates to the field of train control, in particular to a high-speed train control method and a design method of a robust controller of the high-speed train control method. The high-speed train control method comprises the steps: collecting the real-time running state, at least comprising the current train speed and the coupler offset, of a train; calculating state deviations betweenthe current train speed and the coupler offset and between a target speed and a target coupler offset; calculating a state feedback control law; calculating the control force of each carriage according to the state feedback control law and the state deviations; and applying the control force to each of the carriages. According to the control scheme provided by the invention, the control performance can be remarkably improved under the condition of not sacrificing the speed tracking performance; and the control method has the important practical significance.

Description

technical field [0001] The invention relates to the field of train control, in particular to a high-speed train control method and a design method of a robust controller thereof. Background technique [0002] As an important part of rail transportation, high-speed trains undertake major development strategies in terms of national economic development, cultural exchanges, and urban construction. As the main mode of railway passenger transportation in China, so far, more than 9 billion passengers have been transported to the north and south of the country by high-speed trains. Fast and safe has become its hallmark. However, with the continuous increase of the running speed of high-speed trains and the complex and changeable operating environment, the dynamic environment of the train system has deteriorated significantly, which poses a huge threat to the safe and stable operation of high-speed trains. Therefore, it is of great significance to ensure the safe and efficient ope...
