Abstract: A method for filtering at least one signal to be filtered. The filtering being determined based on measurements representing the movement of a rotating shaft. The method includes defining at least one characterisation indicator of the rotating shaft. The characterisation indicator being obtained from a frequency analysis of the behaviour of the rotating shaft (step 120). The method includes determining a filtering template as a function of the characterisation indicator (step 130) and applying the filtering template to said signal to be filtered (step 140).

Abstract: A method for characterising the behaviour of a rotating shaft using equivalent ellipses. The method for characterising the behaviour of a rotating shaft comprises the following steps: acquiring at least two input signals over a predetermined period comprising measurements representing the movement of the rotating shaft (step 10); determining two components of the input signals, the components being orthogonal to each other (step 20); merging the two components into a bivariate signal (step 30); time-frequency decomposing the bivariate signal into spectral elements (step 40); determining an equivalent ellipse for each spectral element (step 50); and extracting at least one characterisation indicator of the rotating shaft based on parameters of the equivalent ellipse (step 80).

Abstract: A method for controlling a rotating shaft by breakdown of measurements of said shaft into stationary and disturbance components. The method for controlling a rotating shaft comprises acquisition of a signal to be filtered (step 160); filtering and breakdown of the signal to be filtered into a stationary component and a disturbance component for each time-frequency pairing of the signal to be filtered (step 170); comparison of the stationary component with respect to a setpoint for each time-frequency pairing (step 190); comparison of the disturbance component with respect to said setpoint for each time-frequency pairing (step 200); and generation of a command of an actuator associated with said shaft such that the actuator modifies a rotation and/or positioning parameter of the rotating shaft (step 210).
