Plotting and Calibrating the Root Locus

Root loci often diverge as system poles shift from the real axis to the complex plane. Key points in this transition are the breakaway and break-in points, indicating where the root locus leaves and reenters the real axis. The branches of the root locus form an angle of 180/ndegrees with the real axis, where n is the number of ...

Root loci commonly diverge when system poles transition from the real to the complex plane.

The breakaway and break-in points signal where the locus leaves and rejoins the real axis. The root locus branches form a 180/n degree angle with the real axis.

The gain peaks at the breakaway point between open-loop poles on the re...
