This thesis focuses in the design, analysis and implementation of a predictive current
controller for the control of a Permanent Magnet Synchronous Machine (PMSM).

The theory regarding the PMSM and converter system is described mathematically in
order to have models to better understand the different problems. Trough the different
parts of the project several approximations are needed to yield solutions to the problems
presented and trough simulation and experiments the hypothesis taken are validated.

This thesis studies the predictive controller including the main problems presented
with its implementation. The effect of changes in system parameters is studied and different
non-linearities are analyzed and compensated. Finally online parameter estimations
are also developed as a way for the compensator to adapt to changes in them.

As a result of the thesis the predictive controller is seen as a simple controller with
excellent performance when the different compensations needed are accounted for.
