Obiettivi formativi

The course has the purpose to provide the fundamentals of modeling, principles of operation and control, main basic knowledge and future developments of electrical drives.

Learning outcomes:

Knowledge of the design and operation of most common and advanced control tecniques in conventional and advanced electrical drives.

New special machines contol.

Modalità di svolgimento dell'insegnamento

The training objectives are linked both to the acquisition of new knowledge, therefore frontal lessons as teaching method and tutorials to include the ability to apply the acquired knowledge through computer and/or laboratory exercises.

This year's teaching could be taught not only at University but in a mixed or remote way.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
