Teaching methods

This is a traditional course: room lessons and homeworks.

Assessment methods

Written exam on the theoretical topics and presentation of a report on the laboratory activity. If the number of students is small, the final exam could change.

Teaching tools

Simulations with Matlab/Simulink

A laboratory with the most traditional electric drive is available.
