Testbed for sensors

to test acceleration sensors used in wind turbines

Problem: The amount of vibration at which a (mechanical) wind turbine imbalance sensor tripped was unknown.
Solution: Prototype of a lineair slider where the sensor could be placed on.
Result: A complete understanding of how the mechanical imbalance sensor worked, and at which amount of imbalance it would trip.

Vision System

to check for 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.

DNPC control of dutch polder ‘Waterlandse Boezem’.

control of the water level using two pumping stations

Problem: The controller had to satisfy complicated on/off criteria, to minimize pumping activity during expensive day hours.
Solution: A Digital Non Modle Predictive Controller to find the optimal pump settings to maintain the water level within the limits
Result: A 5% reduction in energy consumption.

Improved O2 control of wastewater plant.

using the High Performance PID

Problem: Too much variance of the O2 percentage
Solution: Implementation of the High-Performance PID (HP-PID)
Result: An 80% reduction of O2 variations.
