说明：  匀速升温控制是个复杂的过程,具有大惯性、纯滞后、非线性等特点,难以得到精确的数学模型。考虑到这些特点,为提高控制精度,将Fuzzy-PID算法应用于电阻炉温度控制系统,当误差较大时采用模糊控制,误差较小时采用模糊PID控制,实现了2种控制方法的优势互补,在此基础上,给出了Fuzzy-PID控制器设计、硬件结构和软件设计,实验曲线表明该控制算法可以获得满意的控制效果,采用模糊PID控制的效果明显优于常规PID控制。
(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.)
