Abstract
Determining health of a component includes using at least one processor to perform processes including acquiring a plurality of measured values corresponding to the condition indicators. Synchronous noise components are removed from the measured values to provide revised measured values, and the revised measured values are used to determine noise-filtered condition indicator values. The noise-filtered condition indicator values may be used in algorithms to determine the health of the component. Removing synchronous noise components may include determining a predicted value thereof using covariance and autocovariance of the measured values. The component may be a split torque gearbox.
