本文讨论用于改善开环增益可能会有较大变化的反馈系统的动态特性的“等相移网络”的设计方法,并采用了优化的计算程序来求出极、零点的最佳位置,从而得到了一个在计算机上实现的最优设计法。设计中采用了RC网络,因而所得的网络便于集成化。本文提出的方法可以应用于激光稳频、光波波长锁定、超导腔微波稳频、核磁共振稳场、精密运算放大器等高精度反馈系统中。 This article discusses the design of “equal phase-shift networks” for improving the dynamic characteristics of feedback systems that may have large changes in open-loop gain, and uses an optimized calculation program to find the optimal pole and zero location Got an optimal design method implemented on the computer. The design uses an RC network, so the resulting network is easy to integrate. The proposed method can be applied to high-precision feedback systems such as laser frequency stabilization, wavelength locking, superconducting cavity microwave stabilization, NMR magnetic field stabilization, precision operational amplifier and so on.
