“…This method characterized the faults well and can differentiate between different fault classes. In the time-frequency analysis, some methods have been proposed for particular faults such as Randall [79], Williams et al [89], Girondin et al [32], Hood et al [41] and also Ehinger et al [24].…”

Faults or failures are inevitable to occur and their prompt detection and isolation are essential for the dependability of various systems and for avoiding damages to the system itself, persons and the environment. Therefore, the safety of helicopter platforms have attracted the attention of many researchers in the past two decades. In order to deal with these problems, this paper presents an overview of the recent development and current researches in the field of fault diagnosis, including analytical/model-based, signal processingbased and knowledge-based techniques, and also passive/active fault-tolerant control approaches.

Abstract-In the past two decades, the reliability and safety of helicopters have attracted the attention of many researchers. Especially with the development of Unmanned Helicopters, Fault Diagnosis approaches were used for manned or unmanned helicopter platforms. In this paper, a brief state-of-the-art on Fault Diagnosis approaches is presented for helicopters, including analytical model-based, signal processing-based and knowledge-based Fault Diagnosis approaches. A short description of fault types is presented before the main part of the review.

“…Since the autocorrelation computed from OSS is a real signal, this relation to the Fourier transform clarifies that negative scale values need not to be considered since the magnitude spectrum is an even function of frequency. While in [13] the implementation of the scale transform based on (3) was used, in this paper the algorithm for computing the direct scale transform (DST) as presented in [25] was applied. DST is derived from (2), by approximating the integral in (2) as follows:…”
