Modeling for the Calcination Process of Industry Rotary
Rotary kiln is important equipment in heavy industries and its calcination process is the key impact to the product quality. Due to the difficulty in obtaining the accurate algebraic model of the calcination process an intelligent modeling method based on ANFIS and clustering algorithms is studied. In the model ANFIS is employed as the core structure and aiming to improve both its
