Development of a Game Arcade

Control of a cable driven manipulator

Problem: Operators of the hunting simulator had issues with positioning the meat in the lion cage.
Solution: Providing haptic assitance to the operators joystick, allowing the operator to feel when the control system started overiding the operators input to avoid a collision with the wall.
Result: The collision ratio was significantly decreased, while the average velocity was increased.

Vision System

Inspect steel coil inconsistencies

Problem: Steel coils sometimes suffer from inconsistencies in their windings. When this goes unnoticed, it could trip a factory for a few hours.
Solution: Automatic detection of inconsistencies using a camera measurement system.
Result: A fully functional camera measurement system which has been operating for 5+ years in harsh environments.

Customer: 2B-Energy

2-B Energy has introduced an innovative offshore wind power plant concept aimed at a significant lower Cost of Energy than competitors, and intends to commericialise this concept worldwide. Some of the differences with conventional wind turbines are: it is two bladed, it is downwind (the blades are downstream of the tower), it has a lattice tower, it has a unique yaw system. DotX has supplied 2-B energy with the DotX Wind Turbine Controller (see Products) and has helped to develop the 2B6 demonstrator (6MW) which is up and running in Eemshaven, the Netherlands.

Wind Turbine: Controller Tuning

Automating the tuning process

Problem: Wind turbines often run 8 or more PID loops, and many of them have strong interactions. This causes manual tuning to give sub-optimal results.
Solution: An automatic tuning tool which optimizes all the controller parameters w.r.t. the loads, and the power.
Result: The time required to fully optimize the control loops is reduced from two weeks to just two days.
