Mechanical construction
Model Magnetic levitation can be decomposed into three subystems - The ball and coil, coil amplifier, position sensor.
The voltage entering coil amplifier u is proportional to computer output. The amplifier output is electric current i by which we control position of the ball in a magnetic field.
To determine the ball position x is used inductive proximity sensor, whose output is voltage y corresponding to the position of ball in a magnetic field
Model's comunication is based on multifunction input/output card MF614 (A/D and D/A converters) that allow to write/read data with the use of Real Time Toolbox functions
