This page was developed to help student learn how to sketch the root locus by hand. You can enter a numerator and denominator for G(s)H(s) (i.e., the loop gain) and the program will guide you through the steps to develop a sketch of the root locus by hand.
It is not the intention of this page to be used as a generic design tool, it is simply a teaching tool. As such, it is only designed to work with poles and zeros that are relatively small numbers (say between 0 and 20).
