Abstract
A magnetic levitation tellurion demonstration model based on digital control takes an embedded computer LPC 2114 and a peripheral circuit as a core controllor; the current of the electromagnet is controlled through the data collection and processing of the position of a levitation tellurion and current of an electromagnet by utilizing PID algorithm, so that the tellurion has stress in balance in the vertical direction, and the levitation control of the tellurion is further achieved; the external disturbance can be overcome in the digital control method; the tellurion also can regularlly rotate through a rotary magnetic field formed below the rotary magnet; a touch-type liquid crystal display on a master controllor can promote man-machine interaction, thereby facilitating operating control of the tellurion demonstration model by a user; a stepping motor is mounted below a bracket; the stepping motor can step up the tellurion to a preset levitation point through a tray on a screw bolt after the system is electrified; when the gravity and the levitation force of the tellurion achieve balance, the tray is restored to the initial position; and the magnetic levitation tellurion demonstration model is rich in demonstrating and viewing effects due to decoration of LED color lamps.
