Automatic control is a classic engineering subject that has become increasingly important over the last centuries because of its use in almost all industrial fields. Simultaneously, a lot of research efforts have been put into the development of control design methods and theoretical approaches to analysis of control systems. Today, automatic control is a highly active research field, ranging from investigation of theoretical aspects in a mathematical framework to recent industrial challenges and new applications. Over the years, the control field has come to include also some related topics that are relevant in the development of a controller, e.g., sensor fusion and system identification.


The research at the Division of Automatic Control illustrates the wide scope of the control field with projects ranging from theory development to industrial applications covering both core control design and system analysis approaches as well as control-related estimation problems. Besides the obvious relation between control and mathematics, there are also strong links between the research at the division and the fields of mathematical statistics and optimization, with many tools and techniques in common. Furthermore, the division is actively cooperating with researchers in several other fields. Some examples of applications studied at the division are aircraft, industrial robots, heavy-duty vehicles, cars, ships, underwater vessels, medical imaging systems, and power amplifiers.

Research areas

Most of the research projects at the division concern one or several of the following areas:

Optimization for Control
The research in optimization for control is currently focused on efficient optimization algorithms for model predictive control and for robustness analysis of control systems.
Robotics and Autonomous Systems
Improved diagnosis and control of industrial robots and autonomous features in aeronautical or automotive systems are topics studied in cooperation with industry partners.
Sensor Fusion
The research in sensor fusion covers both theoretical and practical aspects of how to merge information from signals of different kinds. The applications concern navigation, collision avoidance as well as target tracking.
System Identification
System identification deals with estimation of mathematical models of dynamical systems from data and both theoretical convergence aspects, software development, and industrial applications are investigated here.

Research Projects

Wallenberg Autonomous Systems Program (WASP)

Wallenberg Autonomous Systems Program (WASP) is one of Sweden's largest ever research programs. The program addresses research on autonomous systems acting in collaboration with humans, adapting to their environment through sensors, information and knowledge, and forming intelligent systems-of-systems.
