Frequency Response Stability Criteria
{"Image DocumentName": "Frequency Response Stability Criteria", "Image ImageDescription": "Two principal methods to assess stability: - Bode Stability Criterion - Nyquist Stability Criterion The Bode Stability Criterion The Bode stability criterion states that a closed-loop system is unstable if the Frequency Response of the open-loop Transfer Function has an amplitude ratio greater than 1.0 at the critical frequency \u03c9c. Otherwise the closed-loop system is stable. For the analysis, \u03c9c is the value of \u03c9 where open-loop phase angle is -180\u00b0", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
