Abstract
Systems and methods for fault detection and diagnosis in a machine. The method includes selecting fault characteristic frequencies of faults, implementing the fault characteristic frequencies as modulating signals, receiving a feedback signal from at least one sensor associated with a machine, applying active modulation using the modulating signals to the feedback signal to obtain modulated signals, and monitoring for a low-frequency fault indicative component from the modulated signals.
