WebUsing the root locus plot, you can determine the value of K for which the poles cross the imaginary axis on the boundary between stability and instability, i.e., the value of K for which the system is marginally stable. This value of K can be found by identifying the point on the root locus plot where the poles are closest to the imaginary axis.
