Embodiment Construction

[0102] In order to illustrate the present invention more clearly, below in conjunction with preferred example and appended Figure 1~5 The present invention is further described. Similar parts in the figures are denoted by the same reference numerals. 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.

[0103] Consider a high-speed train EMU containing four power units, such as figure 1 shown. The cruising speed of the train is 300km / h, and the running resistance parameters of the train and the mass of each power unit are shown in Table 1. The uncertain constant wind resistance encountered by the train during operation satisfies a random noise distribution with a mean of -10kN and a standard deviation of 5. Considering that the train running time domain is [800s, 850s], the initial speed and relative displacement deviation of ea...

Abstract

The invention relates to a distributed control method of multiple power units of high-speed train. The method includes the following steps: S1. using the number of multiple power units of the high-speed train, a train reference speed operation curve, train speed limitation information, and a train friction resistance coefficient and so on as control system input; S2. monitoring and obtaining the real-time speed and displacement feedback information of each power unit of the train in each sampling control period; S3. according to the real-time speed and displacement feedback information of eachpower unit, designing a distributed control method, calculating control output of each power unit and controlling the train; and S4. repeating S2 to S3 until the control process ends. The distributedcontrol method designs a distributed cruise control method for a power-dispersed high speed train according to the characteristic that multiple power units are used by high-speed trains and bullet trains to perform traction and braking, thus the precision of tracking the train and the operating comfort of the train are improved effectively, and energy consumption of operation of the train is reduced to a certain degree.

Description

technical field [0001] The invention relates to the field of rail transit high-speed train control. More specifically, it relates to a distributed control method for multiple power units of a high-speed train. Background technique [0002] At present, with the rapid development of high-speed railways, my country now has the world's largest high-speed railway network with the highest operating speed. As the "brain nervous system" of high-speed railways, the high-speed train operation control system is the core key technology to ensure the safety of high-speed train operation and improve operation efficiency. In order to ensure the safe and efficient operation of high-speed trains, the design of high-speed train operation control methods has become an important research hotspot in academia. The advanced high-speed train operation control method can effectively improve the safety, comfort and stability of train operation. [0003] High-speed train EMUs adopt power dispersion...
