Magnetic Levitation System

The Magnetic Levitation System (MLS) is a classic control problem used in many practical applications such as transportation, magnetic levitated trains, using both analogue and digital solutions to maintain a metallic ball in an electromagnetic field. The MLS is a single Degree of Freedom system for teaching of control systems; signal analysis, using real-time control applications such as MATLAB.

The MLS is a nonlinear, open-loop unstable and time varying dynamical system. The basic principle of MLS operation is to apply the voltage to an electromagnet to keep a ferromagnetic object levitated. The object position is determined through a sensor. Additionally the coil current is measured to explore identification and multi loop or nonlinear control strategies.
