Magnetic Levitation System

Magnetic levitation

Magnetic levitation is a classical technology in mechatronics. It combines electromagnetism and electronics technology, control technology, signal processing, mechanics and dynamics. The technology is widely used in many industrial fields such as magnetic levitation train, magnetic suspension bearing, miniature transmission equipment, measuring instruments, robotic wrist and magnetic levitation educational systems, etc.

The Magnetic Levitation System (Model: GML2001) from Googoltech provides an ideal experiment platform for research and tutorial for undergraduate and graduate students studying classical control theory and modern control theory. Apart from its modern design appearance, laser sensor is adopted as feedback signal to measure moving distance of the floating ball accurately.

In addition, the Magnetic Levitation body (Model: GML2001A) can be provided as a standalone experiment device for any third party or self-designed controller.

System Characteristics:

Students can thoroughly comprehend PID tuning, root locus tuning, frequency domain method tuning, status feedback control method with Matlab software platform experiment course.

Via optional analog control system, by observing and comprehending the structure of control system and the characteristic of driving module, students can construct embedded magnetic levitation controller by combining the analog control system with DSP, ARM, MCU, etc. The embedded discrete control algorithm can be perfected by comparing control results.

Students can select components such as photoelectric, ultrasonic, infra-red distance detecting sensor to build up the magnetic levitation body; and construct complete magnetic levitation system with self-designed embedded controller.

Laser sensor is used as feedback signal. The response time is up to 1.5ms.
