“…In [152], a statistical method for the detection of sensor abrupt faults in aircraft control systems was presented, where the covariance of the sensing signals was used for feature extraction. Recently, a time-domain signal-based diagnostic algorithm was developed in [153] for monitoring of gear faults, by combining fast dynamic time warping (Fast DTW) as well as correlated kurtosis (CK) techniques. The fast DTW algorithm was employed to extract the periodic impulse excitations caused from the faulty gear tooth, and the extracted signal was then resampled for subsequent diagnostic analysis using the CK technique.…”

“…3 for wear in multistage planetary gearboxes. Hong et al [72] described a timedomain approach to diagnose planetary gearbox faults using fast dynamic time warping (DTW) and correlated kurtosis (CK) techniques. They claim to characterize the local gear fault, and identify the corresponding faulty gear and its position.…”

“…More and more methods allow not only for a detection of a fact of deterioration of the technical condition of the transmission, but also the precise determination of location, type and size of the damage. For example in [29], the time-domain fault detection method was presented based on the fast dynamic time warping and correlated kurtosis techniques for this purpose. This method was able to extract periodic impulse excitations caused from the faulty gear tooth using an estimated reference signal that has the same frequency as the nominal gear mesh harmonic and is built using vibration characteristics of the gearbox operated under presumed healthy conditions.…”
