11.1 Closed-loop stability and performance

Description

March 27, 2021
In this lecture, we will learn:
  • Stability and disturbance rejection are determine by the loop gain T(s).
  • The loop gain should have a phase margin of 45-90 degrees and a gain margin over 10 dB for robust stability.
  • Maximizing the gain of T(s) over the widest bandwidth improves disturbance rejection.
