本文根据外反馈的原理,设计了简单实用的附加线路,连接在 DTL—321调节器上,使之能成功地应用在选择性调节系统中。它既不产生积分饱和问题,又不影响原调节器在单独使用时的性能。本文同时介绍了改装后的调节器在实验设备上试验的情况和结果,证明此方法是可行的。 In this paper, based on the principle of external feedback, designed a simple and practical additional lines, connected to the DTL-321 regulator, so that it can be successfully used in selective regulation system. It does not produce the issue of integral saturation, and does not affect the performance of the original regulator when used alone. This article also introduced the modified regulator on the experimental equipment and the results of the test to prove that this method is feasible.
