Introducing undergraduate students to the basic principles of microprocessor system design in power engineering. The student gains knowledge in two fields: microcontrollers and digital control of electrical devices with numerous application examples.

After theoretical lectures and laboratory practice students gain practical knowledge in the field of microprocessors and digital control of electrical drives. Acquired knowledge can be used for solving specific engineering problems.
