WebApr 21, 2024 · Root-Locus analyses the closed loop transfer function by plotting the closed loop poles as some system parameter is varied from 0 to infinity. The parameter to be varied would normally be the open loop DC gain, K. Using this technique the value of K can be determined for a desired stability or damping factor. WebThe poles of sys are complex conjugates lying in the left half of the s-plane. The corresponding damping ratio is less than 1. Hence, sys is an underdamped system. Input Arguments collapse all sys — Linear dynamic system dynamic system model Linear dynamic system, specified as a SISO, or MIMO dynamic system model.
