Modelling and design of control strategies for Permanent Magnet Synchronous Motors (PMSMs)

The aim of this thesis is to provide a wide view of the Permanent Magnet Synchronous Motor (PMSM), from its basic principles to its applications, pointing the interest on the Field Oriented Control (FOC) scheme and proposing different digital control techniques. A Simulink model that takes into account the computing limitation of a real control device and of its hardware components, such as the 3-phase inverter, is designed and used in order to evaluate the dynamic response of the controllers developed. In order to have an example in terms of hardware parameters and limitations, it has been chosen to design the models taking as reference the TMDSHVMTRPFCKIT developer kit and the EMJ-04APB22 ESTUN Permanent Magnet Synchronous Motor (PMSM) . In the first chapter the PMSM structure and its application are introduced. In the second one, it has been given a description of the theoretical concepts necessary to understand the mathematical equations behind the PMSM. As well, all the actors involved in the motor control are introduced. Furthermore, different control techniques are presented. In the third chapter, it is shown the Simulink implementation of the models developed and the design procedure followed to get each controller used. Finally in the conclusions chapter, the results obtained are briefly discussed, summarizing the advantages and disadvantages of the different techniques already explained in the previous chapters.
