Abstract: The enamelling machine oven system is complex, and the effect of the traditional control method is not good.Based on a conventional PID controller，it used the fuzzy control theory, combined with the PID algorithm, to achieve the parameter selfsetting and to solve the problem with the uncertainty of the conventional PID parameters. ZieglerNichols was applied to determine the initial value of PID controller parameters.Then,the fuzzy control theory was employed to revise PID controller parameters, and the PID controller parameters meeting the requirements were obtained. The design controller was simulated in the Matlab environment. The results show that the parameter selfsetting fuzzy PID controller has better controlling effect than a conventional PID controller, and it can also reduce the cost to save energy and improve the economic benefits. 
