Abstract
A method for monitoring a plurality of identical actuators of a common operational assembly having the following steps: operating actuators one by one in similar powering conditions; measuring the energy agent flux during the excitation cycle of each; elaborating for each a time-based curve of the measure flux; elaborating a superposition from curves, and deducing therefrom a normality tracing; isolating the curves showing variations with respect to the normality tracing; and establishing a trouble shooting for each isolated curve, based on variations.
