US4910684A - Method of controlling a rotary kiln during ...

To facilitate a smooth and quick start-up of a rotary kiln, a Fuzzy Logic Control system is proposed, the principal feature of which is to mandate control actions to decrease the specific heat consumption along a straight line from an initial high value to a steady-state value established for the kiln, and then to switch over to an existing steady-state fuzzy logic control mode.

A Neuro-Fuzzy Controller for Rotary Cement Kilns

kiln operator. 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).

FUZZY LOGIC CONTROLLER SIMULATION

Fuzzy control systems interpret the expert human and replace them for performing certain tasks such as control of a power plant. Fuzzy controllers apply decision rules (if-then rules) by making use of critical variables to interpolate the output between the crisp boundaries.
