Abstract: For aluminum powder nitrogen atomization process, it is very important to keep the temperature of the melting aluminum stabilizing in atomization furnace. But atomization furnace is a nonlinear, large delay and uncertain system, and conventional PID controller cannot be competent for this work. A fuzzy-PID hybrid controller is presented to control the temperature of the melting aluminum. The output of the hybrid controller synthesizes the ones of fuzzy and PID controller by a coefficient of weight which makes fuzzy controller work when the error is bigger and PID controller works when the error is minor. The advantages of both fuzzy and PID controllers are integrated in the fuzzy-PID hybrid one. The field application is carried out to illustrate the effectiveness of the fuzzy-PID hybrid controller, and considerable economical benefit is brought about to the enterprise.
