| 摘 要： | 针对工业炉温度控制系统被控参数通常具有时变性、非线性、不确定性等特点,常规PID控制难以满足高精度控制的现状,提出了智能PID算法与PIC1684单片机的温度控制系统。系统利用热电偶检测温度,经温度变送器变换为标准电压信号后送A/D0809转换成数字信号,PIC1684单片机与设定值比较,单片机执行智能PID算法并输出控制量去调节可控硅的触发脉冲,从而实现了温度的实时控制。研究结果表明：该控制器具有静态精度高、自适应能力强、可靠性高、抗干扰性强的特点,炉温控制效果良好。

| Abstract: | Aiming at the problems of the time-varying,nonlinearity and uncertainty of parameters and the status that traditional PID control is hard to meet the high stable constant-temperature requirement,a new system based on intelligent PID controller and PIC1684 microcomputer was investigated in industrial furnaces.This system used thermocouple to measure the temperature of furnace,and the transmitter carried the signal to A/D0809.Then the PIC1684 microcomputer achieved the deviation according to being given value... |
