Im Re Unstable Region Stable Region Marginally Stable Region • Routh - Hurwitz Criterion • Generate a Routh table. • Interpret the Routh table. • Number of poles in the RHP • = Number of sign changes in the first column System Stability • Special case: The first element is 0 • Replace the zero with ε. • Proceed as usual.
