### Lecture 31 - Stability Analysis

Lecture 31 discusses techniques for determining system stability. Of particular interest is how the system stability changes with controller tuning. In this lecture, we review 3 techniques for stability analysis including:

- Routh Arrays
- Root Locus Plots
- Bode Diagrams

There are other techniques such as Direct Substitution and Nyquist Plot Analysis that are not covered in this lecture.
