Title:
LEVITATION CONTROL METHOD FOR MAGLEV SKYTRAIN
Document Type and Number:
WIPO Patent Application WO/2020/029714
Kind Code:
A1
Abstract:
The present invention provides a levitation control method for a maglev skytrain. A permanent magnetic track, made of rare earth permanent magnetic materials, for the suspended maglev train is installed in a sky beam, and interacts with a permanent magnet set on a bogie to create a repulsive force. According to the levitation control method, stable levitation and non-contact operation are implemented by means of the steps of levitation control, travelling by driving, steering control, speed measurement and positioning control, braking, etc. A linear induction drive motor in cooperation with a positioning system allows for safe and stable travel. According to the present invention, the defect of the instability of a levitation system composed of a permanent magnet is overcome, thus improving the stability of the levitation system.
