Martin Enqvist: Research
At the moment, Martin Enqvist is mainly working within the Vinnova Industry Excellence Center LINK-SIC, where he is area coordinator for the aerial vehicles and marine vessels research projects, within the EU project MarineUAS, and in a CENIIT project about Adaptive linearization of electronic devices, where he is project leader. Previously, he has worked in projects funded by the Swedish Research Council and by the Flemish and Belgian governments.
Martin Enqvist's main research interests concern system identification, i.e., data-based modeling of dynamical systems based on measurements of their input and output signals. This is an important topic within the research field of automatic control since most modern control-design methods are model-based. Actually, control-oriented modeling of an unknown system can be much more time-consuming and challenging than the actual control design in many cases.
Some of the research topics that Martin Enqvist has worked on or is investigating right now are:
- Approximation issues in system identification (e.g., linear approximations of nonlinear systems, estimation based on incomplete statistical information)
- Nonlinear system identification (e.g., block-oriented systems, nonparametric models, nonlinearity detection)
- System identification in closed-loop and network settings
- Dimension reduction
- Estimation of inverse models
- Unknown input problems
- Applications: aircraft/rotorcraft, cars, ships, electronic amplifiers
