I-II

Learning Outcomes (valid 01.08.2018-31.07.2020): 

After the course, students will be able to:
1) describe typical applications of electric drives and their performance requirements;
2) calculate the required electromagnetic torque of the motor for various mechanical loads;
3) build simulation models for cascade-controlled DC motor drives and scalar-controlled induction motor drives;
4) tune a PI speed controller based on the mechanical parameters;
5) select the motor and the converter for simple applications.

Content (valid 01.08.2018-31.07.2020): 

Applications of electric drives and power-electronic systems. Equation of motion, typical load torque profiles, gears and transmissions. Cascade-controlled DC motor drives. Permanent-magnet synchronous motor drives, space vectors. Motor and converter selection.
