Systematic Low Order Controller Design for Disturbance Rejection with Plant Uncertainties

Abstract

The research reported herein has concentrated on the development of design methodologies to meet simultaneously several diverse requirements including transient performance, disturbance rejection, robustness, and reliability. The design methodologies developed herein are based on (1) projective controls, which provide a parametrized family of low-order controllers that guarantee certain performance specifications are met and possess free parameters to be used to meet additional requirements (2) the Frobenius-Hankel (FH) norm as a computationally attractive measure of optimality to meeting disturbance rejection and robustness requirements with low-order projective controllers, and (3) the algebraic Riccati equation as a means of characterizing H-infinity-norm-bounding controllers.
