正交试验法在电加热炉温度控制中的应用

The Application of Orthogonal Design Method in Electrically Heated Furnace Temperature Control

本文提出了利用正交试验法整定电加热炉温度控制系统PID参数的方法,详细介绍了正交试验法原理及实现过程,并通过现场试验得到了确定的PID参数;可以看到正交试验法整定PID参数具有省时省力准确的特性;该方法已成功应用在冶钢集团钢研所使用的电加热炉微机控制系统中,证实了这种方法的可行性。

The author proposes to rectify PID parameter in electrically heated furnace by orthogonal design method and gives some details about its theory so as to get the exact PID parameter. This method is much more convenient, correct and feasible, which is used in the electrically heated furnace temperature control system.
