The fault diagnose of advanced amphibious assault vehicle fan pump based on principal component regression

The fan pump hydraulic system of amphibious assault vehicle is prone to fault, an pump leakage model is established by principal component regression. This new modeling strategy can effectively extract on the components which have a strong explanatory role of the dependent variable, it achieves regression modeling in multiple arguments correlation conditions, and allows the inclusion of all the original variables. This model get rid of drawback that the least squares regression can not effectively identify and eliminate the influence of the multiple relativity among factors.
