Ve dnech 25. - 27. Října proběhla mezinárodní konference TRANSCOM 2007 pořádaná Žilinskou Univerzitou. Jak napovídá oficiální název konference "7th European Conference of Young Research and Science Workers in Transport and Telecommunications" byla konference zaměřená obecně na dopravu a spoje. Za KEEZ se aktivně účastnili Ing. O. Černý, Ing. R. Doleček, Ing. Z. Němec, Ing. J. Pidanič a Ing. J. Šimánek. V rámci konference byly předneseny dva příspěvky:

Abstract: The paper deals with our research in the field of control of drive with permanent magnet synchronous motor (PMSM). We focus to development the robust control algorithm for direct drive PMSM. We have designed and simulated two control algorithms. The first of them is a phase current control. This algorithm is based on sinus commutation algorithm of brushless DC motor. We have adapted this algorithm to improve its behavior during generating of higher frequency. The improvement is caused by induced voltage compensation and adaptation of PI constants of controllers. The second algorithm is field oriented control algorithm. Comparison of simulation results of both algorithms is presented in conclusion.

The papers deals with testing stand of tram wheel direct drive and traction synchronous motor with permanents magnet and its loading drive. The maid advantage is utilization of traction motor of nominal power 58 kW and nominal torque 852 Nm. This stand will be used for testing control structures of converters. Power electronics structure and electronics structure of control are described in this paper, too.
