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.
