to test acceleration sensors used in wind turbines
Problem: The amount of vibration at which a (mechanical) wind turbine imbalance sensor tripped was unknown.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 hourscontrol 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.using the High Performance PID
Problem: Too much variance of the O2 percentage
