Abstract
`The root loci patterns which result from changing the balance between the terms in optimal H-infinity stability and performance robustness problems are investigated, The steps for a polynomial analysis are pre sented. These result in two theorems covering the finite starting and the (finite and infinite) terminal points for the root loci of the two types of H-infinity problems, Four examples are given with a root loc i analysis for each of the H-infinity optimal control problems.
