OVERVIEW

The course offers the needed knowledge for the study and development of advanced control systems for electrical dynamic systems, with particular reference to electronic power converters, to guarantee the efficient transformation of electrical energy in the various forms required.

AIMS AND CONTENT

LEARNING OUTCOMES

The main aim of the module is to provide students with the basic notions on the modern theory of automatic controls, and its application in the real world, with the help of the means offered by current electronic and information technology, with particular reference to the study and development of advanced control systems for power electronic converters.

AIMS AND LEARNING OUTCOMES

Attendance and participation in the planned training activities will allow the student to know the essential parts of the modern theory of automatic controls, rich in mathematical content, and to learn the elementary theory of continuous dynamic systems, with a focus on control of converters and electric drives.

At the end of the course, the student will be able to:

• apply the skills and knowledge developed for the correct and rigorous formulation of even complex problems and to set up the solution, using the means offered by current electronic and IT technology, also considering fundamental aspects in the application context;

• solve converters and electric drives control problems using digital simulation tools;

• characterize implementation solutions for the control of power electronic converters.

TEACHING METHODS

The course includes theoretical lectures (50 hours) and laboratory exercises (10 hours). The exercises will be both passive and active, the students will be invited to set up some computer control systems, independently. Attendance is absolutely recommended.

Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's contact person for disability at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns. Contacts of the teacher and the School's disability contact person can be found at the following link Comitato di Ateneo per l’inclusione delle studentesse e degli studenti con disabilità o con DSA | UniGe | Università di Genova

EXAM DESCRIPTION

The exam consists of an oral discussion concerning the whole teaching programme.

ASSESSMENT METHODS

Details on how to prepare for the exam and on the degree of depth of each topic will be given during the lectures. The exam will focus on all the topics covered both during the lectures and during the exercises and will allow the teacher to verify the knowledge of the theory taught and the ability to correctly formulate even complex problems and set their solution.
