Abstract
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.
