Problems solved by technology

[0003] In the guidance control of high-speed maglev trains, the high-speed maglev train with overlapping structure is its unique system. The conventional state feedback control method only satisfies the performance at a certain equilibrium point. Due to the overlapping structure, when the system is far away from the equilibrium point When the system performance deteriorates
Moreover, the conventional state feedback control method does not consider the current balance of adjacent steering control points in the control process, which may lead to the problem that the current at one point is too large, while the current at another point is too small, which is not conducive to the controller and electromagnetic iron work

Embodiment 1

[0038] The overlapping structure of the high-speed maglev train is its unique system. Due to the reason of the overlapping structure, if the conventional state feedback control method is adopted in the guidance system of the high-speed maglev train, it can only satisfy the performance at a certain equilibrium point, without considering The current balance of adjacent guiding control points may lead to the problem that the current at one point is too large, while the current at another point is too small, which is not conducive to the work of the controller and the electromagnet. Therefore, in order to ensure the consistency of the guidance gap, the current balance in the adjacent guidance points and the global stability of the guidance control system, this embodiment proposes a suspension guidance control point based on the current point, the opposite point and the adjacent point. The guidance control method of high-speed maglev train based on information fusion, the relative r...

[0059] refer to Figure 4 , this embodiment discloses a high-speed maglev train guidance control system based on multi-point information fusion. The guidance control system uses the guidance control method in Embodiment 1 to perform guidance control on the high-speed maglev train. Specifically, the guidance control system includes an information acquisition unit, a control processing unit, and a control output unit. Among them, the information acquisition unit is a sensor set on the electromagnet, which is used to obtain the real-time measurement information of this point, the relative point, and the adjacent point, specifically the guiding gap and gap current of the current point, and the guiding gap and gap current of the relative point. , the guided gap and gap current of adjacent points. The control processing unit is connected to the information acquisition unit, and is used to obtain the real-time guidance control amount of each guidance control point according to the r...

Abstract

The invention discloses a high-speed maglev train guiding control method and system based on multi-point information fusion. The method comprises the following steps that real-time measurement information of a current point, a relative point and an adjacent point is obtained; establishing a guiding control law model including information fusion of three guiding control points including a current point, a relative point and an adjacent point; and obtaining the real-time guiding control quantity of each guiding control point based on the real-time measurement information and the guiding control law model. The method is applied to the technical field of guiding control, the idea of nonlinear control is adopted, and when the suspension gap is increased, the increase speed of the control quantity is higher on the basis of a conventional state feedback control method; when the suspension gap is reduced, the reduction speed of the control quantity is higher; in the guiding control process of each guiding control point, the consistency of the guiding gap between the point and the opposite point can be effectively ensured, meanwhile, the current balance between the point and the adjacent point is ensured, and the global stability of the guiding control system is improved.
