    Sep 01, 1998 Two kinds of intelligent, hybrid control systems for a rotary dryer are presented. The main controlled variable is the output moisture of solids and the main manipulated variable is the input temperature of drying air which correlates to the fuel flow. The main disturbances of the process are the input moisture of solids and the feed flow

    A steady state mathematical model of the rotary sugar dryer has been developed. The model comprises two parts; a mass/energy balance model and a transport model for bulk sugar transport through the drum. The model was enhanced and a model-based control strategy was trialled at two sugar factories in feed-forward control
