# 11.1 Closed-loop stability and performance

## 설명

2021년 3월 27일

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.
