Bio

Catalin Arghir obtained his PhD degree from the Automatic Control Laboratory at ETH Zürich in 2019, under the guidance of Florian Dörfler. He received his Master's degree from the Department of Electrical and Computer Engineering at the University of Toronto, where he worked with Manfredi Maggiore. From 2012 to 2014 he was with Murata Power-Solutions Ontario, where he developed digital control firmware for AC/DC switch-mode power supplies.

Research

I'm developing feedback design tools using concepts from nonlinear and geometric control. I focus on applications of control theory to power conversion systems, robotics and motion.
  • In October 2019 I've successfully defended my PhD thesis, titled "Transverse feedback passivation in control of multi-machine and multi-converter power networks", which was examined by Florian Dörfler, Claudio De Persis and Romeo Ortega.
  • About my most recent work, I gave a seminar at University of Waterloo. Some intermediary results were also prepared for the FEPSET19 workshop.
  • At MTNS 2018, I presented a first-principled framework for multi-machine synchronization. Research leading to that was on display at FEPSET17 and NECSYS16.
  • In 2014, I gave an IfA internal seminar about my MEng. project titled "Virtual Holonomic Constraints for Swing-up of the Pendubot: Experimental Results". Supplementary material can be seen here and here.
I'm always open to meaningful collaborations. Connect with me on linkedin, researchgate or google scholar, and find my CV here.
