Stability Considerations
{"Image DocumentName": "Stability Considerations", "Image ImageDescription": "To analyze the stability of the closed-loop system in Fig , we consider the closed-loop transfer function in Eq Setting the denominator equal to zero gives the characteristic equation, In Chapter 11 it was shown that the roots of the characteristic equation completely determine the stability of the closed-loop system. Because Gf does not appear in the characteristic equation, the feedforward controller has no effect on the stability of the feedback control system. This is a desirable situation that allows the feedback and feedforward controllers to be tuned individually.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
