1. 开环转移函数:用来分析稳定度,找出Phase Margin(PM:相位裕度)跟Gain Margin(GM:增益裕度)2. 闭环转移函数:用来测量控制系统性能,如最大超越量、频宽等时与频域性能指标3. 系统不稳定的二个必要条件:开环转移函数的相位延迟180度开环转移函数的相位延迟180度时

Chapter 7_6 Phase Margin and Gain Margin
(about 30 deg worst case) and confirmed it through a visual inspection of the nyquist plot. I would like to generate expressions that read both phase and gain margin directly from the nyquist plot and store them in my assembler view. Visual inspection isn't an o...
gain marginphase marginnonlinear control system本文提出一種找出合可調參數非線性控制系統有關漸近穩定性與極限環之增益邊際和相位邊際的方法。首先用描述函數法將非線性控制系統線性化,然後加入增益相位邊際測試器,並將特性方程式分解成兩個穩定方程式,最後應用參數平面法即可找出常數增益邊際和相位邊際之邊界。依據該邊界...
