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