A method is proposed for performance assessment of PID control loops subject to time-varying disturbance dynamics, which is often observed in industrial processes. The proposed method optimizes overall performance of the processes and presents a PID tradeoff curve which provides a useful lower bound on the achievable performance of the PID controller in terms of both the most significant disturbance...
Multi-scale monitoring approaches, which combine principal component analysis (PCA) and wavelet analysis, have received considerable attention. These approaches are potentially very efficient for detecting and analyzing diverse ranges of faults and disturbances in chemical processes. An improved multi-scale principal component analysis (MSPCA) is proposed for polymerization process monitoring. Improved...
The modeling approach of stacked neural networks based on absolute error criteria is proposed, and applied to inferential estimation of polypropylene melt index. Single neural network model generalization capability can be significantly improved by using stacked neural network model. Proper determination of the stacking weights is essential for good stacked neural networks model performance, so determination...
