The Nonlinear Control Systems Group is a leading Estonian research unit in automatic control, focusing on control theory and symbolic software, supporting fundamental/applied research and teaching.

The research directions of the Nonlinear Control Systems Group are non-linear and robust control systems, modeling of control systems, learning and planning in robotic systems, formal testing and verification methods for distributed and embedded systems.

Since 2016 the Nonlinear Control Systems Group is part of Excellence in IT in Estonia, funded by the European Regional Development Fund for the period 2016-2023.

During the period 2011–2015 then named Laboratory of Control Systems belonged to the Estonian Center of Excellence in Nonlinear Studies (CENS).
