LINK-SIC 鈥� Linköping Center for Sensor Informatics and Control 鈥� is a Vinnova Competence Center for industry-academia cooperation with the general area of control systems and signal processing. The center's operational period was between 2017 and 2023.

The activities within LINK-SIC concern industry-oriented research within areas of vital importance for Swedish system-building industry. This industry sector is crucial for the growth and economical sustainability of the country, and Sweden has a number of successful companies competing on the global market.

LINK-SIC encompasses several of the largest of these companies (ABB Corporate Research, ABB Cranes, ABB Robotics, Atlas Copco Industrial Technique, Saab Aeronautics, and Scania) together with several small and medium-size enterprises (Actia Nordic, Alelion, Senion, and UMS Skeldar). The companies develop products, which sometimes are referred to as cyber-physical systems, in which mechanical and electronic hardware is combined with software, executing model-based algorithms for control and processing of sensor signals.

Four main application areas 鈥� Automotive Systems, Aerial Vehicles, Marine Vessels and Mechanical Manipulators 鈥� are studied within LINK-SIC and some of the challenges that are addressed concern sustainability, safety, reliability, autonomy, ease-of-use, and man-machine interaction. The application challenges are addressed using the core competences of the center 鈥� Sensor Fusion, Data-Driven Modelling, Learning Methods for Control, Control-Oriented Physical Modelling and Optimization for Control Applications.

Research Program

The research program is illustrated by the matrix to the left.

The core competences are strong research areas within the academic partner, and they are crucial for dealing with the industrial challenges described above.

The application areas are tightly connected to the industrial partners. The core competences are essential in all application areas, and hence also for the involved companies.

There are thus excellent opportunities for synergies across both core disciplines and application areas, and between the industrial partners.

Application Areas and Core Competences

Automotive Systems

The application area has the general theme of modeling, control, and supervision of functions in vehicle powertrains. The aim is to develop control systems that can obtain optimal performance, safety, energy utilization and environmental stability.

Aerial Vehicles

The research about manned and unmanned aerial vehicles concerns topics such as robust sensor fusion for navigation, monitoring and control purposes and tools for efficient estimation of models from flight test data.

Marine Vessels

The research within the application area Marine vessels is focused on support and advisory systems for marine automation.

Mechanical Manipulators

The application area mechanical manipulators covers different types of kinematic structures such as serial, closed kinematic chain type, and different wire based crane systems.

WASP at Department of Electrical Engineering (ISY)

WASP Computer Vision Laboratory, WASP Sensor fusion, WASP Vehicular Systems and WASP Optimization for Learning and Autonomy are located at the Department of Electrical Engineering (ISY) on Campus Valla in Linköping.

Data-Driven Modelling

Some of the challenges with data-driven modelling are to handle dynamics, disturbances, mismatches between system and model, nonlinearities, prior knowledge, missing data, and closed-loop or network configurations.

Learning Methods for Control

In this context learning refers to the process of using data to create mathematical descriptions of mechanisms for control and supervision of systems or processes.

Control-Oriented Physical Modelling

This scientific area relates to the cross-scientific discipline of building models of mechanic, electronic, as well as thermo- and fluid-dynamic systems where control inputs and models that have compact physical descriptions are central features.

Optimization for Control Applications

Optimization has become a vital tool for analysis, design and actual control implementations. Increasing demands are put on the computational efficiency of the algorithms, robustness and certifiability, and computational tools.
