Description
 
The Magnetic Levitation system presents this classic control problem of sustaining a metalic ball in an electromagnetic field with both analogue and digital solutions. The suspended body is a 25mm hollow steel ball. In the analogue mode the system is fully self-contained. In the digital mode it operates with MATLAB/Simulink software.
