This paper describes the study and implementation of the radial position control of a bearingless induction motor with divided windings, using intelligent control techniques for optimizing the radial positioning. For the radial positioning, the forces controlled by the internal machine magnetic fields are used. The proposed control methodology used to design a Fuzzy controller with proportional and derivative action, based on a set of control rules formulated in linguistic terms. All the system control is executed by a program developed in the ANSI C language on a DSP TMS320F28335 with floating-point, where two Fuzzy PD controllers are implemented for the radial positioning and six Proportional-integral type controllers for the current control loop. Finally, the simulation and experimental results of the system are presented and discussed, proving the good performance of the intelligent controllers based Fuzzy Logic for radial positioning control for driving the Bearingless-motor.
