Abstract :
THE ROOT LOCUS method solves the problem of finding the roots of the characteristic equation by an extension of concepts now associated with the frequency-response method. The roots describe the natural response of the system, and knowing them permits a solution for any input. Consider a simple single-loop system, shown in Figure 1, for convenience in developing a physical picture.
