Abstract:

Abstract: A novel qualityrelated kernel latent structure projection method was proposed and qualityrelated monitoring was applied in the nonlinear process. Different to the KPLS, the proposed method further decomposes the quality variable space into three subspaces, which can achieve a complete monitoring of the quality which can be and cannot be interpreted by process quality. Meanwhile, the validity of the proposed method was verified by TE simulation.
Key words: kernel projection to quality latent structure; nonlinear process; quality monitoring
