Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

After the course, students will be able to:
1) draw and explain block diagrams of typical vector-controlled and DTC-controlled drive systems;
2) design three-phase current controllers;
3) select current references for various AC motors;
4) build simulation models for drive systems and power-converter systems;
5) explain the most essential relationships between control of AC motor drives and control of grid converters.
