为了防止在间歇操作、超驰调节等场合发生的积分饱和现象,新型气动仪表都考虑了抗积分饱和措施.但是,对于积分饱和现象的专题介绍比较少,而且更缺少明确的数学表达,所以对积分饱和的实质以及它和一般饱和的区别往往容易引起误解.这种情况对仪表的设计和使用都是不利的,本文尽量从数学上对问题加以讨论,并结合一种气动抗积分饱和线路的分析,希望引起有关方面注意.
In order to prevent the phenomenon of integral saturation occurring in intermittent operation, override adjustment, etc., the new pneumatic instruments all consider the anti-integral-saturation measures, however, there are few presentations on the phenomenon of integral saturation and more lack of clear mathematical expression The essence of integral saturation and the difference between it and general saturation tend to cause misunderstandings.This situation is unfavorable to the design and the use of the instrument.This article tries to discuss the problem mathematically as far as possible and combines with a pneumatic anti-integral saturation circuit Analysis, hoping to attract the attention of the parties concerned.
