Abstract

In this paper we present an algorithm capable of drawing automatically accurate root locus plots. It computes all the values of K for which at least one branch of the root locus changes direction abruptly (in that case the characteristic equation has multiple roots), subdivides each branch into segments according to these values of K, and draws separately each segment. Based of the first derivative of K as a function of s, appropriate values of K are computed in order to sample each branch of the root locus at approximately equidistant points. The output of our algorithm compares favorably with the output of MATLAB's rlocus command.
