ONLINE TEMPERATURE CONTROL OF FLUIDIZED-B ED INCINERATOR USING FUZZY ALGORITHM

Automatic control of incinerators for their stable operation has been desired for the preservation of the environment in the factory. An on- line fuzzy control system has been successfully introduced for tempera ture control of the fluidized bed of incinerator for industrial wastes . In this case, manual control can be applied to the plant instead of a PID control system, because of the complexity of the waste materials and the large delay in detection of the temperature change in the flu idized bed sand. On the basis of analyzing the dynamic performance of the process and the know-how of skilled operators, membership function s and fuzzy control rules are selected, then determined carefully for the system. Introduction of the system resulted in almost the same per formance as manual control. Subsequently the operators are freed from manual operation in the control room for an hour.
