Oskar Wigström

Doktor at Signals and Systems

Oskar Wigström is a PhD student in the Automation research group who focuses his research on scheduling of industrial systems. He works on optimization of hybrid systems, where for example energy consumption is to be minimized. His other research interests include robust scheduling and integrated optimization methods. Oskar is also a teaching assistant in the basic automatic control course for engineering physics students and the Linear Control Systems Design master's program course.
