Recommended Prerequisites
Introduction to Electric Drives, Electric Machines I
Teaching Methods
The teaching methodology consists in a small number of seminaries, taught by the teacher for the introduction of the fundamental topics, complemented with a bibliographic survey by the students to deepen their knowledge about these subjects, being supported in this work by a set of tutorial classes.
Learning Outcomes
It is intended with this curricular unit to study the aspects related to the design, performance and implementation of electric drives based on different types of electric machines, using the most recent control strategies, namely those based on Field Oriented Control (FOC) and Direct Torque Control (DTC).
The main results of the learning process include the knowledge of the state-of-the-art of electric drives and allow students to carry out research in this field of knowledge.
Work Placement(s)
