A Linear Closed Loop System Analysis Procedure Using Line Printer Plots of Characteristic Equation Root Loci

Abstract

An existing program that determines the root locus of n'th order polynomials has been modified to provide plots of these loci in the complex frequency plane using a standard line printer. A methodology that combines the computational capabilities of this root locus program with a variable scale graphical display of selectable regions of the complex frequency plane is presented. A listing of the Fortran IV source deck of the modified program and two examples are included.
