在设计自动调节系统或新系统投运时,需要确定调节器正反作用、选择器高或低的功能、前馈信号在加法器中叠加的符号。它们按一般方法是容易确定的,但为设计工作达到表格化以及能用计算机计算打出表格,就需要将这一工作公式化。在通常判断时用 When designing an automation system or commissioning a new system, determine the pros and cons of the regulator, the selector high or low, and the sign of the feedforward signal superimposed on the adder. They are easily identifiable in the usual way, but to make the design work passable and to be able to computerize the form, it needs to be formulated. Used in the usual judgment
