Design and Simulation Software for Controls, Filtering, Signal Processing

Linear control system analysis and design : conventional and modern / John J. D'Azzo, Constantine H. Houpis (1988) 3rd edition. The earlier editions were 1960 and 1981.

This book has an appendix about an Air Force FORTRAN TOTAL, or TOTAL-I.

This is also covered in the 1981 2nd edition.

These D'Azzo and Houpis editions are the only place I have seen TOTAL mentioned.

From when I first learned of MATLAB, I felt that this TOTAL was one of the influences behind it.

TOTAL comes from an MS Thesis

Larimer, S. J. "An Interactive Computer-Aided Design Program for Digital and Continuous System Analysis and Synthesis (TOTAL), School of Engineering, Air Force institute of Technology, Wright-Patterson AFB, Ohio, 1978

So D'Azzo and Houpis write of TOTAL, there is TOTAL I and TOTAL II.

It is supposed to be as easy to use as an electronic calculator. They even give you something similar to an HP-45 scientific calculator inside of it, 4 level RPN stack and 20 storage memories.

So I had assumed that this was with the paper punch cards. It ran on CDC Cyber, SEL 32, and DEC VAX-11/780.

And I think this latter is where they adapted it to be fully interactive on CRT terminals. So the new package was called ICECAP. And it is written in both FORTRAN and PASCAL.

Again, I think TOTAL is a big part of the inspiration behind MATLAB. But today you need much much more than that.

TOTAL has over 100 commands, most pertain to matrix manipulations.

It can hold 12 polynomials, and then these can make 4 rational polynomial functions. These can be your standard for blocks, Pre-Comp, Comp, Plant, and Feedback. But you can reduce it to just 3.

TOTAL II is sold by Integrated Systems, Inc.

Again, just like MatLAB really.

Moves seamlessly from Frequency Domain to Matrix Time Domain. Of course it can get you eigenvalues, and this means real and complex roots to high order polynomials.

Other programs D'Azzo and Houpis mention. One is MatLAB. Others:

MACSYMA by Math Lab Group and Laboratory for Computer Science, MIT.

CTRL-C by Systems Control design.

MATRIXx (later bought by OR-CAD and quite capable, but I don't know if it still exists)

MATLB L-A-S LOGALPHA

MULTI from another Air Force Institute of Technology thesis Porter, D. S. "Design and Analysis of a Multivariable, Digital Controller for the A-7D Digitac II..." 1981

I would say though that today you need much more than what any of these programs do.

Most of the refs are articles or theses, which are much harder to get than books.

So, drawing from:

Linear Control Systems Analysis and Design Conventional and Modern Third Edition John D'Azzo and Constantine Houpis 1988

So, above I talked about the matrix program TOTAL, coming from a thesis by S. J. Larimer, at the Air Force Institute of Technology, Wright-Patterson AFB Ohio, 1978

Now we also have other Air Force Institute of Technology theses listed:

Colgate, A. "INTERAC -An Interactive Software Package for Direct Digital Control Design 1977

Gembrowski, C. J. "Continued Development of an Interactive Computer-Aided Design (CAD) Package for Discrete and Continuous Control System Analysis and Synthesis, 1982

Hernandez, G. "An Interactive Computational Aerodynamics Analysis Program, 1980

Kennedy, A. "The Design of Digital Controllers for the C-141 Aircraft Using Entire Eigenstructure Assignment and the Development of an Inter-Active Computure Design Program, 1979

Logan, G. T. "Development of an Interactive Computer-Aided Design Program for Digital and Continuous Control System Analysis and Synthesis", 1982

O'Brien, L. "A Consolidated Computer Program for Control System Design", 1976

And I am sure that MatLAB arose from this work.
