Fuzzy controller of cement kilns has been one of the first successful applications of the fuzzy control in industry. In 1978, Holmblad and Ostergaard used the first fuzzy controller for a complex industry process, cement kiln. They saw that the results were much better than when the kiln was directly controlled by human (Wang, 1994).
