About Me

Dannis Brouwer is the chair of the Precision Engineering group at the University of Twente focusing on precision motion of mechatronic and robotic systems. The group focusses on the development of model-based methods for the design and control of high-precision systems.

The main goal of the design activities is to continue, elaborate and to ‘scientificate’  'Design Principles for Precision Mechanisms' by using a model-based approach. By developing new and advanced modeling methods like flexible multibody modeling, complex system designs can be thoroughly analyzed, understood, designed and optimized.  

The main goal of the control activities is to develop improved motion control using an adaptive model-based approach. Models are available from design or analysis and online updating ensures matching the actual system dynamics. These models then used for improving precision through (disturbance) feedforward control, disturbance rejection control or feedback control optimization.

Dannis M. Brouwer received his MSc. degree in mechanical engineering, in 1998, and a postmaster (PDEng) degree in mechatronic design in 2001 from Eindhoven University of Technology, Eindhoven, the Netherlands. He has 8 years of industrial experience with Philips Centre for Industrial Technology (CFT), Eindhoven, the Netherlands and Demcon Advanced Mechatronics, Enschede, the Netherlands. In 2007, he received the doctoral degree in mechanics from the University of Twente, Enschede, the Netherlands. He was appointed full Professor at the University of Twente in 2020 and is now chairing the Precision Engineering lab which includes 5 assistant Professors. He has (co-)authored over 50 refereed journal articles, 90 conference contributions and 8 patents on a variety of subjects including flexure mechanisms, kinematics, macro and micromanipulators, variable impedance robotics and precision engineering. In 2015 he received the prestigious personal VIDI grant for his large range of motion flexure research, where he was ranked 1st out of 48. For three years he has served as a Director-at-Large for the American Society for Precision Engineering and he has been Associate Editor for Precision Engineering for 8 years.
