(三)积分调节及比例积分调节器 由于比例调节器在调节终了时会产生余差,在生产过程中,有些被调参数要求严格控制在给定值,因此,就采用积分调节器。积分调节器。它的作用原理是,只要被调参数的偏差存在(即调节器的输入存在), (C) integral regulation and proportional integral regulator As the proportional regulator in the end of the adjustment will have a margin, in the production process, some of the parameters to be adjusted strictly controlled at a given value, therefore, the use of integral regulator. Integral regulator. Its principle of action is that as long as the deviation of the adjusted parameter exists (ie the input of the regulator exists)
