在工作频带ω≤ω_1上的反馈,受限于渐近整体稳定(AGS)单环系统。此系统包括一个饱和环节,其环路增益频响被限定为单频的,并从指定的频率ω_b 越过0 dB 水平线到该频率的左边。如果将回输系数 T_0作为 Bode 最优截止 T_B,就能得到反馈的极大值,满足 Popov绝对稳定判据,给出: The feedback over the operating band ω ≤ ω_1 is limited by the asymptotically monolithic stabilization (AGS) single loop system. The system includes a saturation loop whose loop gain frequency response is limited to a single frequency and crosses the 0 dB horizontal line from the designated frequency ω_b to the left of the frequency. If the feedback coefficient T_0 is taken as Bode optimal cut-off T_B, the maximum value of feedback can be obtained, which satisfies the Popov absolute stability criterion and gives:
