This paper introduces a new methodology for fault diagnosis of rotating machinery in complex industrial process. In this fault diagnosis system, multi-scale principal component analysis (MSPCA) is used. The main contribution of this paper is the use of the MSPCA technique in the fault diagnosis based on vibration analysis in rotating machinery. Their(More)
This paper deals with the modelling and simulation of wind turbine driven by induction generator. Usually in mechatronic systems, several types of energy are involved. By its nature of a power conserving description of a system, the Bond-Graph method is especially practical when several physical domains have to be modeled within a system simultaneously.(More)
In this paper, a new approach on nondestructive evaluation by ultrasonic signal is proposed. The work is based on a parametric spectral analysis with linear prediction for a sharp and precise analysis. The paper contains a description of quantitative analysis method of rocks acoustic properties and a description of a qualitative analysis method based on(More)
