The Design and Application of Hybrid Intelligent Control System for Rotary Kiln Process in Alumina Production

This paper describes the successful application of a hybrid intelligent control system to perform the real time control of rotary kiln for alumina production. The hybrid intelligent control strategy is explained with special emphasis on the adaptive fuzzy control and rule-based expert control. The hybrid intelligent control software package was developed based on the DCS platform. The software package has been found to provide good economic benefits in its successful application in a real rotary kiln process.
