The value of our the company is reflected in the people that run it. Controllab is a home for fine staff of engineers with a wide experience in the areas of mechatronics, modeling and simulation, embedded systems and more.

My name is Christian Kleijn and I am the president of Controllab. I studied Electrical and Mechanical Engineering at the University of Twente. In 1995 I was asked by the Control Laboratory of the University of Twente to investigate the potential of a software package for dynamic modeling and simulation that was developed at the laboratory. As a result the company Controllab Products B.V. was founded and the software package 20-sim was released. During the years we have build up a lot of experience in the design of scientific software, mechatronics and control. As a result I became active as an engineering consultant advising companies in 1998.

Hello, my name is Paul Weustink. I studied Electrical Engineering of the University of Twente and received a masters degree at the Control Laboratory of this university. I joined Controllab in September 1998 as scientific programmer and expert on real-time control. My daily job at Controllab is to design and develop everything that is interesting for the 20-sim package, and for this I have frequent contact with our customers. This means that I'm busy with modeling and simulation, mechatronics, robotics, and hybrid systems. I am also working on software projects for third parties. A fine example it the Simquest software. This package allows students to run all kinds of simulations to learn physics, with an extensive authoring facility for teachers. I developed the most of the core of this software.

Hello, my name is Frank Groen. I studied Electrical Engineering at the University of Twente. In April 1999, I joined Controllab as a scientific programmer and expert on the simulation part of 20-sim including the presentation of the simulation output like 3D visualizations. I have build up considerable experience in real-time control. We have been invited numerous times to give advice how to activate stranded projects. A good example is our last project at the Maritime Research Institute (http://www.marin.nl) where we have been working on control systems of two towing cranes. We have modeled the whole control loop in 20-sim, including PLC-control, PC-control, AC-motors, sensors and crane dynamics to find out the weak points. As a result we have improved the crane response by more than 50%.

My name is Peter Visser. I have studied Electrical Engineering at the University of Twente. After my graduation in the fall of 2002 I started with my PhD. During my PhD research I gained a lot of experience in modeling of multidisciplinary systems and real-time embedded systems. One of the modeling tools being 20-sim, I kept a good relation with Controllab. So when Controllab offered a position in 2007, whereby I could translate part of my research and experience in a industrial application (the 20-sim 4C-application) I gladly accepted. I am currently working on the second release of 20-sim 4C and the design and implementation of embedded systems.

Hello, my name is Jolanda Boelema. I joined Controllab on the 3rd of November 2008. The objective is to make the life of Christian, Paul, Frank and Peter a little easier by doing the administration for them so they can focus on the technical things. I work at Controllab every afternoon from Monday to Thursday. I like being a part of this team very much, the people are nice, the work very diverse, all in all a great job.

My name is Hiwot G.Differ and I am from Ethiopia. I studied Electrical Engineering and received a masters degree in Control Engineering at the University of Twente with cumlaude. During my thesis, I had the opportunity to work on physical modelling and practical realization with 20sim and 20sim 4C. So when I was offered a position in controllab products where I get the chance to experience industrial applications of my study, I gladly accepted. I am presently working on design of a thermoslab setup and a mobile webpage application for monitoring 20sim 4C enabled targets

My name is Marcel Groothuis. I have studied Electrical Engineering at the University of Twente. In my MSc assignment, I've succesfully designed and built a distributed Hardware In The Loop simulation setup using 20-sim and RTAI Linux. After my graduation in 2004, I joined the the Control Engineering group of the University of Twente to start with my PhD on multi-disciplinary design of mechatronic systems.During my PhD research, I've used 20-sim a lot for modeling, simulation, co-simulation and controller code generation for many different targets including DSP's, PC's, ARM CPU's, PowerPC's and FPGA's. One of my research topics was about model management. In 2010 Controllab offered me the opportunity to join them for adding addition of model management features to 20-sim and to help Peter with 20-sim 4C and the design and implementation of embedded systems. I joined the team in January 2011. I'm currently working on the development of a new version of the TorsionBar setup and on the addition of new embedded targets to 20-sim 4C.

Hello, my name is Maarten Meijer. Currently, I am studying Elektrical Engineering at the University of Twente. At the study Electrical Engineering, it is usual to finish the Bachelor's phase with an individual research assignment. For me, it became possible to investigate the connection of Simulink with 20-sim 4C at Controllab, which was a nice and challenging assignment. After a successful completion thereof, I got the opportunity to keep working at Controllab on part-time basis, an opportunity which I would not resist.
Currently, I am, among others, occupied with the design of an actual software implementation of this connection between Simulink and 20-sim 4C.
