Anotace:

The course provides the basic terms and knowledge in electric drives and in the issues related to this discipline as well. The lectures are focused on the basic of electric drives logic control, continuous control and also discrete control, and on the characteristics of used controllers in practice. Further, the basic control structures of drives with DC and AC machines are explained.

Požadavky:

Sufficient knowledge of electric machines (construction, principles, characteristic) and power electronics converters (topologies, principles, characteristics, control).
