Guidelines for the Selection of Weighting Functions for H-Infinity Control

Abstract : This report provides insight into the selection of H-Infinity (H.) Control weighting functions that help shape the performance and robustness characteristics of systems designed using the Hoo and V-Synthesis Control methods. Background material regarding sensitivity functions, loopshaping, and Hoo Control is followed by a discussion of general engineering guidelines for the design of Hoo Control weighting functions. In addition, unresolved design issues and alternatives are presented. Thus, this report presents practical rules-of-thumb and identifies issues and alternatives in the design of weighting functions for Hoo Control.
