Biography

Ph.D. student since 2012.

My research interests are in automatic tuning of PID controllers. The research considers autotuners for both single-input single-output as well as multivariable systems. The autotuners we have developed have been evaluated in simulations and on real processes with good results. The Matlab/Simulink versions of my developed autotuners are available in this git-repo.

For a popular science description of my research, read my story Kontroll-Kalle styr fabriken (in Swedish).
