In my thesis I briefly introduce the direct torque control and then the field-oriented control, which I explains the operation of simulink. In addition, I show in the field-oriented control two possible controllers, the PI and the Fuzzy logic controller. The main purpose of my dissertation is to present the Fuzzy logic, to design and implement this controller in the matlab simulink file to provide a basis for comparison between PI and Fuzzy controllers. I would like to thank to Viátor Pou for helping me to understand how the field-oriented control works for Miguel Delgado, who has provided a lot of valuable advice, but last but not least to my supervisor, Dr. Luis Romeral, who has followed my writing, and guided me to prepare this thesis.
