In this paper, a new nonlinear reconstruction algorithm is proposed for handling the multimode problem in the industrial processes. The contributions are as follows: (1) in different batch cycles, the transition patterns may follow different trajectories and reveal different characteristics. After the operation patterns change, the two neighboring modes(More)
Noise interferences and the lack of observation data are two main problems when implementing blind source separation. This paper introduces a BASS method which eliminates noise interferences, and meanwhile, uses sparse component analysis to fit the undetermined situation. Firstly, based on the BASS mathematical model including linear noise affixed, we built(More)
