Root Locus Analysis & Design • A designer would like: – To know if the system is absolutely stable and the degree of stability. – To predict a system’s performance by an analysis that does NOT require the actual solution of the differential equations. Introduction: Root Locus Controller Design. In this tutorial, we will introduce the root locus, show how to create it using MATLAB, and demonstrate how to design feedback controllers that satisfy certain performance criteria through the use of the root locus.
