Control of electrical drives 1 IS-FEE-10003

The aim of the subject is to develop the theoretical and practical student's knowledge on energy conversion in open loop and closed loop automatically controlled electrical drives. Discussion of condtruction and features of electrical drives. Students introduction into safety regulatoin when working in enviroment with converter controlled electro-mechanical drive systems. Students acquaint with the methods of analysis and mathematical description of electric drive system.
Examples and construction of automatically controlled electrical drives for energy conversion. Fundamentals of electric drives: moment of inertia, different types of frictional torques and examples of active torque, effect of gearing, torque - speed characteristics of electrical motors and generators, multi-quadrant operation of electric motors and converter controlled drives, stable and unstable operating points, power flow and losses in a three-phase induction motor and three-phase synchronous generator, reference frame transformation, variables observed from several reference frames.

Requirements:
Students should have basic knowledge in the field of mathematics, electrical physics, circuit theory, digital and analog electronics, fundamentals of computer science. The general requirement is that student has studied engineering for at least 2 years. In some cases prerequisites are defined.
