| 摘 要： | GB/T 21860-2008(液体化学品自燃温度的试验方法)是液体化学品自燃温度测定方法的标准,若采用常规PID(比例、积分、微分)温度控制存在超调会影响试验结果精确度.根据坩埚炉低温区间升温速度快、高温区间升温速度慢的特点,以及国家标准中要求以30℃和3℃进行温度调节,对坩埚炉当前温度和所需调节温度两个变量进行模糊化处理,建立此坩埚炉的模糊控制规则库,构造坩埚炉温度的模糊PID控制器.在仿真情况下,模糊PID控制没有超调,控温精度达到目前国外产品同等水平.模糊PID控制器的设计,为实际试验过程中的坩埚炉温度控制器设计积累了经验,寻找到了方向.

| Abstract: | National Standard GB/T 21860-2008 of China(Liquid chemicals-Test method for the auto-ignition temperature) was used to test the temperature spots of liquid chemicals' auto-ignition temperature.Crucible furnace afford the chemical reaction's environment,and if it was adopt the conventional PID control,it would be come out overshoot and affect the precision of the test result.According to the feature that crucible furnace's heating speed fast in low temperature range and slow in high,and temperature was regul... |
