Review of Control Strategies and Model Estimation Techniques applied to Bearingless Induction Machine with Divided Winding

The bearingless induction machines exhibit significant nonlinearities, creating the need for implementation of control systems that combine the classic control techniques with modern model observers. Aiming to contribute to the development of new systems, this paper presents an overview of the main control and estimation strategies implemented in laboratory using the induction bearingless machines with divided winding, highlighting the advances and difficulties arising from these type of systems.
