Abstract

The paper reports on the modelling and control of. large colour-picture-tube(CPT) glass furnace. It is a complex and highly nonlinear plant with various noises . Based on the normal operating records and some simple experiments without interrupting the production, a set of rough models was obtained. Referring the models, a compound adaptive algorithm which consists of modified PID algorithm, feedforward compensation, nonlinearity compensation technique and selftuning control was proposed to control the five-input and five-output plant. The results of a long-run operation of the on-line computer control indicate that the modelling and control are suitable for the glass furnace and are very effective
