Early diagnosis of failures can prevent financial losses and industry downtime. In this article, the author proposes an early fault technique for rotor-bearing faults. The proposed is based on recognition sound signals. measured analyzed three states system: system under normal operating conditions, with faulty bearings, rotor friction. original feature extraction method described, namely, 1/3 ...

Dynamic system fault diagnosis is often faced with a large number of possible faults. The purpose this paper to propose an efficient method for such situations. To avoid intractable combinatorial problems, sparse estimation techniques appear be powerful tool isolating faults, under the assumption that only small faults can simultaneously active. However, studied in framework <italic xmlns:mml="...
