Abstract
In this article, the detection of a fault on the inner race of a roller bearing is presented as a problem of optimal estimation of a hidden fault, via measures delivered by a vibration sensor. We propose a linear model for the transmission of a vibratory signal to the sensor´s diaphragm, that we validate with numerical simulations in two situations: with or without a fault. In both cases a Kalman filter is deduced and simulated
