This paper presents a method for decreasing the steady-error of a closed-loop control system by making a transfer zero with self-lifting method. The steady-error can be adjusted to zero theoretically. By this method a system with advantages equivalent to those obtained by the ordinary open-closed-loop method can be attained without any rigorous synchroregulated setting. Therefore, the difficulties caused by synchro-sampling can be avoided, and this method can be used in the system wherein serious trouble will be met with using the open-closed-loop method. It is found that adding a transfer zero to a deep feedback system by self-lifting does not cause more difficulties in the system stability design. In principle, this method can replace the open-closed-loop method used in the automatic control system. Some examples are given to show the application of this method in electrical measurements.

本文介绍一种减少闭环调节系统中的静态误差的方法,即利用自举制作传输零点,理论上可把静态误差调节到零。本方法所能达到的指标与一般开闭环系统相同,但可大大简化同步调节设备,并可用于不适宜使用开闭环系统的场合。在一个强反馈系统中,加入自举零点并不增加稳定性设计的困难。因此原则上这种方法可普遍代替开闭环系统用于各种自动调节场合。文中举了几个例子来讨论本方法在电测中的应用。
