Synopsis:

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.

Requirements:

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.

7.Motion equation, solving of mechanical problems in electric drives; torques.

8.Analysis of operating conditions, electromechanical transient phenomena.

9.Drives with separately excited DC motors, mathematical model.

10.Drives with series DC motors, mathematical model.

11.Drives with induction motors, mathematical model.

12.Speed control of drives with induction machines, principle of field oriented control a direct torque control.

13. Drives with synchronous motors, mathematical model, start up.

14. Excitation systems of synchronous machines, speed control of drives with synchronous motors.
