COMPUTER AIDED ROBUSTNESS ANALYSIS OF DYNAMIC SYSTEMS

Abstract

The robustness analysis of multivariable dynamic systems is discussed. A computer package for robustness analysis of mulivariable dynamic systems, called ROBUST, is described. The programs have been written in FORTRAN. They compute different robustness measures for controlled dynamic systems, and display them graphically. These measures have been proven to be very useful to the control system designer in analyzing the robustness properties of multivariable systems. The programs have been implemented on a VAX 11-780 computer and are used together with an interactive graphics package called VGRAF.
