Abstract
A method for determining a steady state operating condition of a machine includes determining whether a current machine speed of the machine is within a defined range of operation, determining whether a step change in output power of the machine has occurred, determining a first duration of time elapsed since the machine speed was last outside of the defined range of operation, and determining a second duration of time elapsed since a most recent detected step change in output power of the machine. The machine is deemed to be in a steady state condition whenever the current machine speed of the machine is within said defined range of operation, and the first and second durations of time exceed respective minimum values defined therefor.
