Rilevazione di rotture in sistemi fisici a componenti aleatorie

A. Fassò
The work considers the problem of detecting a change (soft-failure) in the dynamic structure or in the input structure of a real input/output system. The system diagnostic is based on the ARMA representation of the real system, where only output data are available. Under the no-rupture hypothesis the statistical properties of the residuals or the so called innovation process are well known. In the present paper, through the definition of a general rupture model, the...
