Modelling and H∞ control of a rotary dryer

摘要

This paper describes the modelling and the control strategies of a drying process. The plant uses a co-current rotary dryer to evaporate moisture of a waste product generated by olive-oil mills, called alpeorujo or two phase cake. The paper shows the development of a model based upon first principles combined with experimental results. A control strategy has been tested under simulation based on H controllers for the outer loop in this process.
