Automatic Control

The research done by the automatic control group is concentrated on the theory and applications in Control Engineering and is based on a firm knowledge of system theory, control engineering, simulation methods, optimisation methods and numerical algorithms. Given the multidisciplinary nature of control, the research done by the group targets several application areas in particular. The main focus has changed over the years. The current research is concentrated on process control, marine engines and applications, power electronics and electrical machines, mechatronics, maintenance and fault diagnostics, system dynamics and cybernetics.

The weight of traditional process control now has a smaller role than it used to have. Control methods are developed more, for example, to study active vibration attenuation as well as how to control electrical manufacturing processes and human-machine systems.

Vibration control of electrical machines involves using first principles modelling and estimating the model’s parameter, e.g. by using nature-inspired optimisation techniques, developing advanced control algorithms and conducting research on time-varying systems with time-periodic parameter variations.

Theoretical research on control engineering mainly focuses on two different areas: time-varying differential systems and adaptive robust control. The former mainly studies systems with time-varying periodic parameters, while the latter provides a theory of self-adaptation for complex, interconnected, dynamic systems under the influence of the environment.
