Abstract
In finite dimensional linear systems theory, stability and Transient performance of a closed-loop control system are directly related to the location of the closed-loop roots of the characteristic equation in the complex plane. Frequently, it is necessary to adjust one or more system parameters in order to obtain desirable root locations. Therefore, it is important to know how the roots of the characteristic equation migrate as the parameters vary. To this end, the “root locus method” was introduced by Evans in 1948 and has been developed and utilized extensively in control engineering practice.
