摘　　要：温度控制在现代自动化工业现场非常普遍:比如在冶金、化工、建材等各类现代工业中,均广泛使用反应炉、加热炉等设备,这类设备在工作过程中往往需要对其温度进行准确的测控。常规的温度控制算法往往是采用PID等基本过程的控制算法,但是PID往往难以达到很多场合对于控制速度、精度等方面的要求。尝试使用遗传算法来进行温度控制,并进行了Multisim仿真分析。仿真结果证明新的算法,其控制效果改进明显。Temperature control is very popular in modern automatic industry. For example, different kinds of reacting furnaces and heating furnaces are usually applied to such industries as metallurgy, chemical, and building materials. Tempera- ture of these equipments usually needs to be accurately controlled during their operation process. PID and other basic process control algorithms are often adopted in the conventional temperature control algorithms, but they have no ability to meet the speed and precision requirements which cannot be neglected in many industry sites. Genetic algorithm is adopted in this paper to control the temperature of equipments. Multisim simulation analysis was conducted. The simulation result indicates that the new algorithm is considerably effective to improve the control quality.
