Intended learning outcomes *

Aim of the course is to give the students ability to design and analyse control systems for electrical energy conversion. The course focuses primarily on control of voltage-source converters, both in electrical machine drives and connected to the grid.

After completed course the student should be able to

  • contruct and apply models for the electrical energy conversion process, mainly machine, grid and load models;
  • understand the different time scales on which key variables in the electrical energy conversion process evolve;
  • close various control loops with suitably selected controller structures and with appropriate parameter choices;
  • analyse the stability and sensitivity of control loops;
  • understand the principles of estimation of variables which cannot be measured and the implications of estimation on the system performance.
