Abstract
In order to better identify the fault of rotor system, one new method based on kernel orthogonal local fisher discriminant (KOLFD) is proposed.Considering kernel mapping and iteration-orthgonal idea,training data with supervision information was mapped to kernel space, computed local with-class scatter and between-class scatter, constructed kernel fisher discriminant function. To ensure the minimum reconstruction error during deimensionality reduction, algorithm joined the orthonormal constraints condition,found optimal basic projection vector by iterative orthogonal approach.Then testing data was mapped by this vector and got new data's class information by neighbor classifier,and eventually realize fault diagnosis.The experiment of rotor fault diagnosis shows, KOLFD algorithm has better effect to other manifold learning algorithm.
