A Linear and Nonlinear Systems Analysis Tool: Line Printer Plots of Characteristic Equation Root Loci, Bode and Popov Plots of System Transfer Functions

Abstract

A computer program to perform dynamic systems analyses and plot the results is presented. Linear systems and a large classification of nonlinear systems representing engineering, scientific, and economic disciplines can be modeled to permit application of the computer program. Two examples are given to demonstrate the capabilities of the analysis tool. The mathematical model of a missile guidance and control system is analyzed and a ratio of polynomials representing the closed loop transfer function of a high performance model follower aircraft is evaluated. Linear differential equations to the 100th order having real or complex roots can be studied. System characteristic equation root loci and system transfer functions are plotted.
