Study, application and comparison of control techniques for a bearingless machine

Magnetic levitation is a phenomenon that allows objects to be suspended in the air using forces capable of counterbalancing gravity. This technology has applications in areas such as urban transport [1], wind turbines and bearingless machines [2], standing out as a relevant field for innovations and advanced studies. This article aims to present the study, application and comparison between two types of control for magnetic levitation in a permanent magnet motor for rotor position control in one degree of freedom (DoF): the control with active rejection of disturbances (ADRC) and a Proportional-Integral-Derivative (PID) control.
