A FORTRAN IV Program to Compute the Inverse Laplace Transform and Plot the Response of a Linear System Subjected to a Forcing Function

Abstract

An existing program, which determines the inverse Laplace transform of a quotient of two polynomials, provides expanded systems analysis capability. The program complements a Root Locus Program and a Frequency Response Program. The program uses a self-contained complex arithmetic routine and also a self- adjusting variable scale plotting technique. The plotting is done on a standard line printer and gives a time history plot of system response for a variety of input forcing functions. A listing of the FORTRAN IV source deck and the corresponding flow chart of the program is shown in the appendixes. Also, several examples are given to introduce the user to the operating procedures and capabilities of the program.
