BAE 3023 Root Locus Sketching Rules Negative Feedback
RL Rules for Negative Feedback BAE 3023 • Root Locus Sketching Rules (negative feedback) 1. Locus exists on real axis where the number of poles and zeros to the right is odd. 2. Roots follow branches from poles to zeros or infinity as K increases 3. Number of branches equals number of poles 4. Number of branches to infinity is number of poles minus number of zeros. 5. Branches to infinity follow asymptotes at the following angles:
