Synopsis:

The course explains the basic building blocks of the electric drive. The designof components, electrical drives, typical load characteristics. Further are discussed the basic control structures for drives with DC and AC motors and components required for their implementation as the structure of a control computer circuits to switch from analog signals to digital and implementation regulators themselves in digital form.

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

Syllabus of lectures:

1.Definition of electric drive, logic control drives.

2.Continuous control, transfer functions, static and dynamic behavior of a controlled system.

3.Transition from analogue to digital signal processing, time sampling and amplitude quantization.

4.Differential equations and digital control algorithms.

5.Digital system in the time and frequency domains.

6.Calculation of PSD controller.
