Many papers related to this topic can be found in the bibliography; however, just a modest
percentage of the introduced techniques are developed to a Technology Readiness Level (TRL)
sufficiently high to be implementable in industrial applications. This paper is focused precisely on
the review of this specific topic. The investigation on the state of the art has been carried out as
a systematic review, a very rigorous and reliable standardised scientific methodology, and tries to
collect the articles which are closer to a possible implementation. This selection has been carefully
done with the definition of a series of rules, drawn to represent the adequate level of readiness of
fault detection techniques which the various articles propose.Unión Europea (7PM / 2007-2013) / ERC n. 78533
