Lecturer:

Tutor:

Supervisor:

Department of Electric Drives and Traction

Synopsis:

The course perfects based knowledges about the control of electric drives. For design of modern electric drive controller it is necessary to manage the system per unit system, normalized quantities and basic control architectures. Students work with controllers based on modern microprocessors and digital signal processors. There is possible to get requainter with top end products in drive technology area.

Requirements:

Participation on labs, solution of tasks.

Syllabus of lectures:

1. Modern controlled drives structure, per unit system, normalized quantities

2. Support means for microprocessor controller development

3. Program realisation of the basic algorithm microprocessor controllers

4. Modulation program solution of a converter for asynchronous machine supply (AM)

5. System equations of an AM as ground of modern control methods
