Abstract :
This paper proposes a new distance function - power spectral density divergence to monitor machine condition .The distance function carries full information of time series model ARMA (m, n). The calculating example shows that it is more sensitive than I-divergence, J-divergence, and Bhattcharyya information distance to the changes of machine conditions.
