Abstract
This course covers modeling and control concepts of modern drive systems and provides a deeper understanding of the dynamic operation of electric machines. Different aspects arising in the control and design of electric drive systems are investigated. The exercises are used to consolidate the concepts discussed.
Objective
The objective of this course is to convey knowledge on control strategies of different types of electric machines and on design principles of variable speed drive systems. A dynamic modeling of the electromechanical system is investigated, enabling the proper design of cascaded speed, torque/current controllers. In addition, a brief insight into basic inverter circuits applied in advanced motor drive systems is provided. Exercises are used to consolidate the presented theoretical concepts.
