Basics of SISO Feedback Controlled Systems

  • Oded Yaniv
Part of the The Springer International Series in Engineering and Computer Science book series (SECS, volume 509)


In this chapter we present the basic properties of single-input single-output feedback systems without considering robustness issues. First the notion of gain margin, phase margin, bandwidth and cross-over frequencies are defined and discussed. Then it is explained why it is so important to decrease the controller bandwidth and in this regard the high-frequency-gain is defined.
