Description: Uniform temperature control is a complex process with large inertia, pure time-delay, non-linear features such as it is difficult to obtain precise mathematical model. Taking into account these characteristics, in order to improve control accuracy, the Fuzzy-PID algorithm is applied to resistance furnace temperature control system, when a larger error when using fuzzy control, error smaller fuzzy PID control, the achievement of the two kinds of control methods complement each other, On this basis, given the Fuzzy-PID controller design, hardware structure and software design, the experimental curve indicates that the control algorithm can be satisfied with control effects, the use of fuzzy PID control better than conventional PID control.
