Problems solved by technology

The verification methods in the prior art either use the guidance control system as a whole for verification, which has the disadvantages of complex models and long running time; or use a single guidance unit as a whole for verification, which has the disadvantages of lack of authenticity and large errors

Embodiment Construction

[0030] As we all know, during the operation of the maglev train, due to various disturbances, it will have lateral displacement and deviate from the centerline of the track. Therefore, in order to ensure the safe and stable operation of the train, in the control system of the high-speed maglev train, a guidance control system must be designed to exert active guidance force on the side of the train. The guiding system is composed of several guiding units. The present invention realizes the decoupling of force through ingenious mechanical design, so as to separate a guiding unit from the guiding system and consider it separately, such as figure 1 As shown, a single guide unit is mainly composed of a train suspension frame (optional but not limited to including support arm, suspension frame L 1 , L 2 , R 1 , R 2 , beams, longitudinal beams, etc.), guide electromagnets on both sides of the side rails and their supporting guide sensors and guide controllers. like figure 2 As ...

Abstract

The invention relates to a magnetic levitation guide control simulation system, on one hand, force decoupling is realized through mechanical design, and a single guide unit is independent from the system and is considered independently, so that a model structure is simplified; on the other hand, the coupling relation (information interaction relation) between the adjacent guide control loop and the opposite guide control loop is comprehensively considered, and the gaps between the suspension device (maglev train) and the tracks on the two sides are kept near a rated value (within a preset range) through simulation control, so that the fluctuation range of the gaps is within an allowable value; the method not only considers closed-loop control loops of respective suspension points, but also considers information interaction between adjacent and opposite loops, is strong in simulation authenticity, high in accuracy and strong in matching performance, and also can realize a redundancy function.

Description

technical field [0001] The invention relates to the field of simulation control, in particular to a maglev guiding control simulation system for simulating and researching a high-speed maglev device (maglev train). Background technique [0002] With the rapid development of maglev technology, there are now maglev trains and operating systems that can achieve high-speed operation. However, before the maglev train is officially put into operation, it is necessary to conduct preliminary debugging on the train and the operating system to ensure the normal performance of each key equipment and avoid major safety accidents. [0003] Taking the maglev guide as an example, the maglev train will be displaced laterally and deviate from the centerline of the track due to various disturbances during operation. Therefore, in order to ensure the safe and stable operation of the train, in the control system of the high-speed maglev train, a guidance control system must be designed to exer...
