Combining Traditional and Neural-Based Techniques for Ink Feed Control in a Newspaper Printing Press

To achieve robust ink feed control an integrating controller and a multiple models-based controller are combined. Experimentally we have shown that the multiple models-based controller operating in the training region is superior to the integrating controller. However, for data originating from outside the multiple models training region, the integrating controller has the advantage. It is, therefore, suggested to combine the two techniques in order to improve robustness of the control system.
