Abstract

This thesis describes the development of an analog MIMO Quantitative Feedback Theory (QFT) CAD package for the automation of the multivariable control design process. The CAD package is capable of carrying a design from problem setup through the design process to a frequency domain analysis of the compensated MIMO system. The package automates the selection of the weighting matrix, formation of the square effective plants, the polynomial matrix inverse required to form the equivalent plants, generation of stability, tracking, disturbance, gamma, and composite bounds, loop shaping, design of the prefilter elements, and the frequency domain analysis of the completed design. Disturbance allocation is automatically performed while generating tracking bounds. The package allows gain scheduling to be used in the weighting matrix. The improved method may be applied for the case of 2x2 effective plant. The package is implemented using Mathematica for use on the Sun Workstations.
