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.
