91340 - ADVANCED ELECTRIC DRIVES M

Conoscenze e abilità da conseguire

The course aims to provide a deep knowledge on the vector control of AC electric motors. At first, starting from dynamic equation, a control model on d-q axes of the following AC machines will be obtained: AC and DC Brushless Motor; Induction Motor; Synchronous Reluctance Motor; IPM Motor Using modern simulation methods based on Matlab/Simulink tools participants will learn how to design the main control architecture scheme for torque/velocity and position including the effect of torque disturbance as well.

Metodi didattici

The course is delivered in English and includes face-to-face lectures (theory and calculations) with connection also in streaming for students who follow from home via the "Teams" platform.
The lessons are carried out with the aid of multimedia systems and can also involve practical exercises in which students are divided in small groups and utilize software for the simulation of hybrid and electric traction systems (Matlab / Simulink),  solve problems and discuss the results among themselves and with the teacher.

In addition, professors receive students by appointment for clarification and personalized tutoring.

The teaching material will be made available at the end of each lesson through the “Teams” platform.
Mathematical models will be used for numerical modeling and computer simulation with Matlab / Simulink 

Modalità di verifica e valutazione dell'apprendimento

The exam will take place at the end of the course according to the official exam session calendar.
The examination is composed of a practical project and an oral discussion on the simulation and design of an electric vehicle.

The evaluation of the project is expressed out of thirty (a score greater than 30 results in obtaining a grade: 30 with honors).

The exam will last approximately 60 minutes.
The evaluation indicators are:
- Ability to use knowledge (25%)
- Ability to connect knowledge (25%);
- Mastery of technical language (15%);
- Ability to discuss topics (20%)
- Ability to deepen the topics (15%)

The grade will be determined and communicated at the end of the oral exam.
