Embodiment Construction

[0053] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following is an example of a superconducting electric levitation train. The vehicle-mounted magnet is a racetrack-shaped superconducting magnet. The present invention is described in detail in conjunction with the accompanying drawings and specific embodiments, but it should not be understood To limit the present invention.

[0054] System structure such as figure 1 As shown, the induction current data generated by the superconducting magnet in the 8-shaped zero-flux coil when simulating the train movement is calculated through the field-circuit-motion coupling theory, and the state sample library is obtained after calculating a large number of different operating states. Through machine learning The method is used to train the system to improve the detection accuracy of the system. When the train is running, the system selects the state data that matches the train op...

Abstract

The invention relates to a control method of a superconductive electric aerotrain capable of realizing static floating, comprising the following steps: calculating induction current data generated bya superconducting magnet in an 8-shaped zero flux coil in simulation of train movement by a field-road-movement coupling theory, so as to obtain a state sample library in different movement states; when the train runs, vehicle-mounted and ground sensors detect the train running state in real time, the signal is transmitted to a central control mechanism to be compared with the state sample library, and state data conforming to the train running state at the moment are selected therefrom, so as to control a regional electric supply station to be conducted to the coil in a certain phase sequenceto generate travelling wave magnetic field to suspend the train; when the train is in a static state, direct current is conducted to the coil by the regional electric supply station; when the train speed is lower than a vehicle floating speed, the regional electric supply station supplies electricity for the 8-shaped zero flux coil; otherwise, not supplying electricity. The control method overcomes the defect that the electric aerotrain cannot suspend in a static state or a state with low speed, and can realize control on the train.

Description

technical field [0001] The invention relates to the fields of maglev transportation, control engineering, superconducting magnets, etc., and in particular to a control method for a superconducting electric levitation train that can realize static levitation. Background technique [0002] The Electric Suspension (EDS for short) train is based on the principle of motion. When the train is running, the magnetic field line of the on-board magnet cuts the track coil to generate an induced current. , when the train reaches a certain speed, the magnetic lift force can balance the gravity, and the car body floats. The vehicle-mounted magnet can realize levitation, guidance and propulsion at the same time, and the system has the ability of self-stabilization and recovery. [0003] According to the type of ground track, electric levitation can be divided into induction plate type and zero magnetic flux coil type. The zero-flux type generally adopts a structure that combines an 8-sha...
