The design of Push-down magnetic levitation system
Abstract— Magnetic levitation technology has the characteristics of no friction, no pollution, low noise, etc.,
so it has very important value in aerospace and mechanical manufacturing. In recent years, with the
development of new high magnetic materials and electromagnetic theory. At present, it has become a hot
research field of major universities and research institutes. At the same time, the magnetic levitation system
is a complex and unstable system with mufti-degree of freedom, strong coupling and nonlinear fastness.
Therefore, the magnetic levitation control system has become a hot spot and a difficult point in the field of
control science. In this paper, a hardware platform of push-down magnetic levitation control system is
constructed. The magnetic field of the floating magnetic field on the vertical component is collected by the
Honeywell 3503 sensor placed diagonally. The linear signal is converted into an electrical signal and
amplified by the operational amplifier. The STM32 reads and writes control information and uses it for the
digital filtering algorithm and the run control algorithm to apply the calculated data to the power amplifier
component to drive the helical coil to generate a corrected magnetic field. Keep the float in dynamic balance
and achieve the desired control effect.
