Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] First, the magnetic levitation experimental device applying the control method and control device of the embodiment of the present invention will be described. The magnetic levitation experimental device generates magnetic force through two electromagnets to ensure that a levitating part with a certain length is levitated in space and is used to detect levitation under test. The position of the component is used as a feedback signal, and the levitation attitude of the levitation component to be tested is adjusted by adjusting the magnetic force of the electromagnet to complete the magnetic levitation experiment process.

The invention provides a control method and control device of a magnetic suspension experimental setup. The control method of the magnetic suspension experimental setup comprises the following steps that a suspension height target signal of a first magnetic suspension portion and a suspension height target signal of a second magnetic suspension portion are respectively generated according to the preset experimental scheme; the suspension height of the first magnetic suspension portion and the suspension height of the second magnetic suspension part are obtained, wherein the suspension heights are obtained through a sensor part; feedback control is respectively conducted on the electromagnetic force of a first electromagnet and the electromagnetic force of a second electromagnet; feedback control is conducted on the electromagnetic force of the second electromagnet; in the feedback control process, the suspension height target signal of the first magnetic suspension portion and the suspension height target signal of the second magnetic suspension portion are adjusted. By means of the control method and control device of the magnetic suspension experimental setup, lifting control for a tested suspension part can be complete, pitch angle control can also be conducted, and the requirements of magnetic suspension experiments are fully satisfied.
Description
technical field [0001] The invention relates to the field of scientific research experimental devices, in particular to a control method and a control device for a magnetic levitation experimental device. Background technique [0002] Magnetic levitation technology originated in Germany. As early as 1922, German engineer Hermann Kemper proposed the principle of electromagnetic levitation. With the development of electronic technology, control engineering, signal processing components, electromagnetic theory and new electromagnetic materials and the progress of rotor dynamics, maglev technology has made great progress. In recent years, maglev technology has been widely used in many fields, such as maglev trains, active control maglev bearings, maglev balances, maglev small transmission equipment, maglev measuring instruments, maglev robot wrists, maglev teaching systems, etc. [0003] Based on the broad application prospects of the above-mentioned maglev technology, the exis...
