Torsten Wik

Biträdande professor at Chalmers, Electrical Engineering, Systems and control, Automatic Control

Torsten Wik is Professor in the Automatic control research group. He focuses his research and teaching mainly on process control, involving methods and theoretical aspects as well as direct applications. Methods include optimal control, model reduction and systems with model uncertainties. The applications are in general energy saving, environmental and biological systems such as water treatment, recirculating aquaculture systems (RAS), and LED lighting in greenhouses. Torsten is also involved in Volvo vehicle applications, aiming at reduced fuel consumption and increased use of electric propulsion.
