【Abstract】 A optimal setting method of a kind of cascade processes under if-then rules is studied. First, the optimal setting problem of cascade processes is described. A method is proposed, in which if-then rules are used to describe the relationship between the changes of set points for each sub-process and the final product quality. The fuzzy (optimization) problem is transformed into a crisp optimization problem by Tsukamoto′s fuzzy reasoning method and the optimal set points for each sub-process are obtained. Simulation on the optimal setting for reheating furnace (temperature) shows the effectiveness of the proposed method.更多还原
