A simple method for oscillation diagnosis in process control loops
A simple method for the diagnosis of oscillations in process control loops is presented. The new method is based on the cross-correlation between control variable and loop output and it is shown to correctly diagnose the two most important reasons for oscillations in control loops in the process industry, namely external oscillating disturbances and static friction (stiction) in control valves.
