我们知道如果在一个自动调节系统中引入了纯滞后,它会使的调节质量显著下降,所以在设计一个自动调节系统时都尽量避免在所设计的系统中引入纯滞后。有些情况下由于工艺本身决定或者测量仪表按装位置具有特殊要求时(例如PH测量中电极位置)不可避免地会引入了纯滞后,在这种情况下由于系统中引入了纯滞后调节质量会显著下降,为此就需要采取一些办法来克服纯滞后给调节质量带来的影响。下面本文就来介绍 We know that if the introduction of a hysteresis in an automatic adjustment system, it will bring about a significant reduction in the quality of regulation, so in the design of an automatic adjustment system try to avoid introducing pure hysteresis in the system designed. In some cases it is inevitable that a pure hysteresis will be introduced as a result of the process itself or the special requirements of the measuring device for the mounting position (for example, the electrode position in a PH measurement), in which case due to the introduction of a purely hysteretic adjustment mass in the system, Decline, for which we need to take some measures to overcome the impact of pure lag to adjust the quality. The following article to introduce
