Abstract
An oscillation controller operates on engine speed or RPM data from a pump or pumping unit associated with a wellbore operation. The oscillation controller determines a measure of variability, such as a bandwidth, for the engine speed over a rolling time window and compares the measure of variability to an oscillation bandwidth threshold. The oscillation controller determines that erratic behavior or oscillation is present when the measure of variability exceeds the oscillation bandwidth threshold, and for such instances measures a duration of erratic behavior with a variability timer. If the oscillation controller determines that the erratic behavior has subsided, the variability timer is cleared. The oscillation controller generates at least one warning whenever the variability timer exceeds an oscillation warning threshold. The oscillation controller mitigates erratic behavior by downshifting (or shifting to neutral) at least one gear of the pump or pumping unit if the variability timer exceeds an oscillation mitigation time threshold.
