The control circuit of the magnetic levitation experimental device

Abstract

The invention provides a control circuit of a magnetic suspension experimental setup. The control circuit of the magnetic suspension experimental setup comprises a first control panel and a second control panel which are the same in circuit structure. The first control panel and the second control panel respectively comprise a sensor interface, a proportion differential regulation circuit, a signal modulation circuit and a driving circuit, wherein the sensor interfaces are connected with a sensor part and used for receiving measuring signals, the proportion differential regulation circuits are connected with the sensor interfaces and used for conducting proportion differential regulation on the measuring signals, the signal modulation circuits are connected with the proportional differential regulation circuits and used for conducting overlapping and modulating on the measuring signals undergoing proportion differential regulation and preset static working point voltage signals to obtain modulation control signals, and the driving circuit is connected with the signal modulation circuit and used for outputting exciting currents to corresponding electromagnets according to the modulation control signals. The two independent control panels are set up in the control circuit by the utilization of simulation circuits, the circuit structure is simple, current signal collection is not needed, the link of integration is omitted, fault points which can appear are reduced, and the reliability is high.

Description

technical field [0001] The invention relates to the field of scientific research experimental devices, in particular to a control circuit of 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 existing research methods...
