Observing Process Data by Contek Systems Ltd
“The root-cause of many control problems can be rather more subtle than poor PID tuning: see this tutorial for a selection of some control-related problems solved by Contek over the last few years.”
U-Tune Tuning Calculator
Calculate proportional-integral tuning parameters for process controllers using the results of an open-loop step response.
The calculator supports the common controller algorithms and parameter types and provides two sets of parameters, one for fast and the other for slow responding loops.
