Abstract
A method of evaluating the performance of a control system using a computerized device includes calculating a ratio of a first area and a second area associated with a peak value of a signal associated with the control system, comparing the ratio with a predetermined value for the ratio, determining a cause of oscillation in the control system based on the comparison of the ratio with the predetermined value for the ratio, and providing a diagnosis of the cause of oscillation in the control system.
