Learning Outcomes
Upon successful completion of this course, students should:
a) know the construction of a permanent magnet synchronous motor,
b) know the vector control technique for AC motor drives (induction and modern permanent magnet)
c) be able to experimentally determine the parameters of a servomoto controlr system and
d) know basic design elements of a servomotor system (sensors, motor selection according to application, etc).
Course Content (Syllabus)
The contents of the semester course “Servomotor Systems” within the specialization on Electrical Energy is as follows:
a) Basic principles of electromechanical energy conversion, permanent magnets, reference frame theory, transformation between reference frames and dynamic models of ac electric machines.
b) Power converters, PI controller, speed and position sensors (design and operation) and types of modulations.
c) Vector control methods of an induction generator (direct and indirect methods, dynamic performance), direct torque control (DTC) method of induction motors, brushless dc motors (design and control), non-salient type brushless ac motors (design and control) and salient type brushless ac motors (design and control).
d) Laboratory exercises.
