This paper exposes the development of a magnetic levitation plant and interface for control the position of a suspended permanent magnet and for monitor the control signal. Its interface have a didactic purpose to allow the students to observe how the control variable of the system changes with perturbations, as well as the design of a PD controller for a linear approximation of a non-linear system. The implementation is composed of the controller circuit (OPAMP and Hall Effect sensor), the power circuit (transistor and electromagnet), and a microcontroller to communicate with the graphical interface through computer. The graphical interface was developed with the GUI editor of MATLAB. Different tests have been performed with the prototype, and they verified that the designed controller worked properly keeping the levitating object in the desired position.
