Supervisor:

Department of Electric Drives and Traction

Synopsis:

The course is based on knowledge about the control of electric drives. For a 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. It is possible to get raquainted with top end products in drive technique area.
