  • Method for monitoring an electromagnetic actuator type apparatus
    Patent number: 10955478
    Abstract: A monitoring method for monitoring equipment of electromechanical actuator type, the equipment including a three-phase electric motor, the monitoring method comprising the following steps: measuring three-phase currents powering the three-phase electric motor; projecting the three-phase currents into a Park reference frame; performing an ensemblist empirical mode decomposition processor the quadrature current coupled with a blind source separation process in order to obtain source components; from among the source components, automatically selecting a first set of source components sensitive to a first defect, and a second set of source components sensitive to a second defect; constructing a first virtual defect signal and a second virtual defect signal; and extracting a first set of signatures representative of the first defect from the first virtual defect signal, and extracting a second set of signatures representative of the second defect from the second virtual defect signal.

  • METHOD FOR MONITORING AN ELECTROMAGNETIC ACTUATOR TYPE APPARATUS
    Publication number: 20200116792
    Abstract: A monitoring method for monitoring equipment of electromechanical actuator type, the equipment including a three-phase electric motor, the monitoring method comprising the following steps: measuring three-phase currents powering the three-phase electric motor; projecting the three-phase currents into a Park reference frame (Iq) ; performing an ensemblist empirical mode decomposition process (30) on the quadrature current coupled with a blind source separation process (40) in order to obtain source components (IC, . . . , IC10); from among the source components, automatically selecting a first set of source components (ICI, . . .
