1.串级调节温度控制串级调节系统从总体来看,它仍然是一个定值调节系统,它和单回路控制相比,在结构上增加了一个与之相联的副回路。这种到回路控制,也经常称为串级控制器,它是对主回路(印发令控制器)作校正,另外要一种能够逐步达到需要数量的定位方法,能安排一个适宜的温度计划表,否则副回路控制器和普通的单回路控制器没有什么不同了,换言之,即输入的参数只能在某些限定之内才可使用,或者是开一关,或者是连续控制,PD控制器是能够适应这个目的。因为,如果一个区域发生控制偏差,对物料的温度产生干扰,就可以从发令控制器对它进行校正。
1. Cascade Control Temperature Control Cascade control system as a whole, it is still a fixed value adjustment system, compared with the single-loop control, the structure of the increase of a secondary circuit associated with it. This loop-to-loop control, often referred to as a cascade controller, corrects the main loop (print command controller) and additionally provides a method of positioning that can progressively achieve the required quantity, and can schedule a suitable temperature schedule Otherwise, there is no difference between the secondary loop controller and the ordinary single loop controller. In other words, the input parameters can only be used within certain limits, either on or off, or continuously controlled. The PD controller Is able to adapt to this purpose. Because, if a region of the control deviation, the temperature of the material interfere with, you can order it from the controller to correct it.
