Title: EES Field Oriented Control
Short Code: EES FOC
ECTS Credits: 1
Organizer Details: Prof. Dr. Alberto Colotti

Active participation in the three days of course is required.

The course is part of the EVA EES.


Decision Date: 1. November 2023 
Start Date: 1. Dezember 2023 
End Date: 15. Dezember 2023 
Date Details:

Three course days, details will be comunicated to the participants.


The course is part of the EVA-EES (electrical energy systems) which is proposed by different schools. The goal of the EVA-EES is to strenghten the knowledge in the field of electrical energy, drives and conversion. The whole cycle consists of  7 courses:

EVA-EES EDD: Electric Drive Design
EVA-EES PV: Photovoltaic Systems
EVA-EES AS: Ancillary Services for Transmission Grids – Technology, Market and Operations
EVA-EES ERT: Electrical Railway Technology
EVA-EES HS: Hydrogen Systems
EVA-EES FOC: Field Oriented Control
EVA-EES ESM: Energy storage and e-Mobility

Description (max. 300 characters):

The EES FOC course covers the fundamentals of the field oriented descriptions of permanent magnet motors and explains their physical and mathematical backgrounds. The structure of modern servo systems is explained and the special topics of internal PM machines and of synchronous reluctance machines are shown.

The EES FOC course is  given in two different settings. The lecture part covers the theoretical backgrounds as the mathematical models and algorithms. In the lab section practical task are assigned to be worked out on servo systems of three different manufacturers.
