Abstract

Aiming to improve the fault detection ability of FD-KNN in the nonlinear and multimodal process, this paper proposed a K-nearest neighbors fault detection method based on varimax rotation(Rot-KNN). Firstly, it implemented varimax rotation in observed data set to obtain an orthogonal space. Next, it implemented FD-KNN in the new orthogonal space to detect faults. At last, it proposed a fault diagnosis strategy based on contribution chart. A nonlinear simulation example and the Tennessee Eastman(TE) processes of a typical nonlinear industrial process prove that the method is effective for the latent variable fault diagnosis. The experimental results indicate that the proposed method outperforms the PCA, FD-KNN and PC-KNN.
