Abstract
The main content of the article is to simulate the magnetic suspension system with a functional control of the air-gap and devise the magnetic suspension circuit with the functions of air-gap measure. First of all, apply the dynamic simulation of MATLAB, through the drawing diagram to establish Mathematical model of the magnetic suspension air-gap control system for the single magnet, use the method of feedback linearization to deal with nonlinear model. Then to design the test board that use PIC16F877 microchip for core, the input of analog signals into a gap and have the function of the air-gap measure, process and storage the sampling data, finally display the relevant technical data through the LCD(Liquid Crystal Display). The system is simple, stable and reliable operation; also more easily to achieve a reasonable, accurate air-gap measurement control, the results can be very intuitive read out on the LCD. Based on magnetic suspension system with a functional control be simulated and the magnetic suspension circuit with the functions of air-gap measure be devised, the magnetic suspension technology will be more in-depth applied for the future.
