Sliding mode Control to position control of Magnetic Levitation System

This article proposes a control law for a magnetic levitation system using the sliding modes technique based on differential geometry. The purpose of this controller design is the regulation of the sphere position. This control law includes a state observer-type speed estimator, this in order to have the presence of all the states of the system, fulfilling the presence requirement of the complete state. Results of evaluation of the control validity law designed for the magnetic levitation system are shown through the execution of several simulations.
