TECHNICAL TRIAL METHOD

摘要

A technical test method for evaluating at least one operating parameter of a device over a sequence of a plurality of operating stages, each stage corresponding to a stable value of at least one operating setpoint of the device. The method including at least sampling values of the at least one operating parameter over time, filtering the sampled values in order to obtain a filtered signal for each operating parameter, calculating the variance of the sampled values for each operating parameter in a sampling window during the operating stage, calculating the absolute value of the time derivative of the filtered signal for each operating parameter and changing the value of the at least one operating setpoint when, for each operating parameter, the variance of the sampled values and the absolute value of the time derivative of the filtered signal are less than respective predetermined lower thresholds.

1. A technical test method for evaluating at least one operating parameter of a device over a sequence of a plurality of operating stages, each stage corresponding to a stable value of at least one operating setpoint of the device, the device comprising at least the following steps for each operating stage:
sampling values of the at least one operating parameter over time; filtering the sampled values in order to obtain a filtered signal for each operating parameter; calculating a variance of the sampled values for each operating parameter in a sampling window during said operating stage; calculating an absolute value of the time derivative of the filtered signal for each operating parameter; and changing a value of said at least one operating setpoint when, for each operating parameter, said variance of the sampled values and the absolute value of the time derivative of the filtered signal are less than respective predetermined lower thresholds over at least a predetermined minimum duration.
