摘要
用于实验室材料样品烧制及性能测试的硅钼炉，是一类大惯性控制对象。作者采用经验规则控制与ＰＩＤ控制相结合的方法，设计了硅钼炉经验规则控制器和ＰＩＤ控制器，由硅钼炉温度偏差大小选择不同的控制器，从而实现对硅钼炉温度的有效控制。该控制系统的温度测量误差ｅｍ≤０．１℃，控制稳态误差ｅｓ≤１℃，测试材料样品的时间也大为缩短。
The Si Mo furnace used for sintering laboratory sample material and performance test is a kind of high inertial control object. The author designed the experiment rule controller and PID controller for the Si Mo furnace, and one of the controllers was selected according to the temperature differential degree, and thus the effective control of the furnace temperature is realized. The temperature measurement error(e m)of this control system is equal to or less than 0.1 deg C;and the static control error (e s) is equal to or less than 1 deg C,and less time is needed to test the sample.
