Teaching Methods

The course consists of 40 class hours in order to allow the student to acquire the knowledge of the main typologies of electrical drives and their employment in electric propulsion systems. The course consists also of 20 hours of classroom exercises, which will be carried out by means of suitable simulation software and experimentally in laboratory: these will enable the student to develop the ability to apply the knowledge acquired during the lectures, especially regarding the control system design of electrical drives for electric propulsion systems. Teaching will be delivered mainly face-to-face, integrated and “augmented” with online strategies to guarantee a novel and inclusive attendance.

Verification of learning

Students will be assessed by means of an oral examination, which will consist of some questions regarding the topics covered during the course. The student will have to demonstrate a fair knowledge and understanding on the operation and control of electric propulsion systems and drives at least. Students will have to show also a fair ability to apply this knowledge. In this regard, some of the questions asked during the oral examination will concern the topics addressed during classroom exercises, namely design and simulation of electric propulsion systems and drives.
The score of the oral examination will be out of thirty. To pass the exam and, thus, achieving a score no less than 18/30, the student must demonstrate a fair knowledge and understanding of the main topics addressed during the course. In order to achieve a score of 30/30 cum laude, the student must show instead an excellent knowledge and understanding of the course topics.
