Based on problems existed in the furnace, such as variable parameters, strong interference, non - linear charac- teristics, its optimum air- fuel ratio difficult to be determined, this paper puts forward a new fuzzy control of variable do- main method based on the satisfaction function. Firstly the state parameters of heating process is get online and the are - fuel is evaluated by satisfaction function, in which the evaluation results and the furnace temperature change is set as the input of fuzzy control of variable domain to get the best real - time air- fuel ratio, thus ensuring the stove ...
