ABSTRACT:
A method of and apparatus for evaluating the performance of a control system are disclosed. The method of evaluating the performance of a control system includes calculating a ratio of a first area associated with the signal and a second area associated with the signal. The method also includes comparing the ratio with a predetermined value and determining a cause of an oscillation in the control system based on the comparison. The apparatus for evaluating the performance of a control system includes a processor operable to execute a first function configured to calculate a ratio of a first area associated with the signal and a second area associated with the signal. The first function is also configured to compare the ratio with a predetermined value and determine a cause of oscillation in the control system based on the comparison.
