GML1001 Magnetic Levitation System

Description Magnetic Levitation System The Magnetic Levitation System (MLS) is composed of an LED light source, an electromagnet, an optoelectronic sensor, amplifier module, an analogue control module, data acquisition card, and a steel ball, etc. Its structure is simple, yet the control effect is very intuitional and interesting. One can easily levitate one or more steel balls in a steady-state position and keep them floating. This system synthesizes main experimental contents in control area and satisfies many experiment requirements such as automatic control, control theory, and feedback system, etc, which are suitable for UG or PG course designs and algorithm research as well. The MLS is a typical non-linear open-loop unstable system. By passing a certain amount of electric current through the electromagnetic winding, it will generate an electromagnetic force. By regulating the electric current in the circuit, the electromagnetic force can be adjusted to be equal to the weight of
