Magnetic Stabilization of DC Motor

In the experimental set-up, one extreme of a flexible beam attached to the motor shaft, and with a permanent magnet fixed on the other end, is constructed.

The controller is conceived by using vibrational control theory and implemented by just processing the time derivative of a Hall-effect sensor signal. This controller is realized by utilizing analog electronics via operational amplifiers. 

The experimental platform results in a low-priced device and is useful for teaching control and electronic topics.
