Development of Graphical Pole-Zero, Root-Locus, Bode, Nyquist, and Nichols Responses Using the OPTSYSX Program.

Abstract

This thesis discussed the modification of and additions to an existing Optimal Systems Control FORTRAN Program (OPTSYS) originally obtained from Professor Arthur E. Bryson of Stanford University. This program has been subsequently redesigned to run interactively on the IBM 3033 VM/CMS by Lieutenant Commander John G. Hoden, and additions by Commander Harry A. Diel provide the user with a highly accurate graphic time response to a system designed using the OPTSYSX program. The addition of the FORTRAN program OPTGRAPH gives the user the capability to obtain classical analysis (Pole-Zero Map, Root Locus, Bode, Nyquist, and Nichols) of transfer functions, calculated for a system designed with the OPTSYSX program. The OPTGRAPH program uses high resolution precision plotting software to provide the user with highly accurate frequency response plots. This series of programs permits users to rapidly carry out simulation, analysis, and design of Optimal Systems Control problems in a totally interactive mode. Originator-supplied keywords include: OPTSYSX computer program, Pole-zero, Root-locus, Bode, Nyquist, Nichols, Transfer function, Open loop, Noise, Compensator, and Fortran. (Author)
