Stability Analysis

This lab covers the basics of stability analysis, including bounded-input bounded-output (BIBO) stability, Nyquist stability analysis, and the Routh Hurwitz coefficient test. Students complete activities in which they apply each approach to a real control system.

This is lab 5 of 6 in the course, Control System Design and Analysis.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Determine BIBO stability of a first- and second-order system.
  2. Use Nyquist plots to examine the stability of a third-order system.
  3. Examine stability using the Routh-Hurwitz criterion.
  4. Experimentally validate stability of a closed loop system.
