MATLAB and Simulink Control
MAGNETIC LEVITATION MODEL
A compact one dimensional strongly non-linear unstable magnetic levitation system to be controlled from within a MATLAB/Simulink environment running on a PC.
The Magnetic Levitation Apparatus shows control problems with non-linear, unstable systems. The apparatus consists of a steel ball held in a magnetic field produced by a current-carrying coil. At equilibrium, the downward force on the ball due to gravity (its weight) is balanced by the upward magnetic force of attraction of the ball towards the coil. Any imbalance and the ball will move away from the set-point position. The basic control task is to control the vertical position of the freely levitating ball in the magnetic field of the coil.
