Mixed H2 and Hinf Performance Objectives I: Robust Performance Analysis
Khemin Zhou, Keith Glover, Bobby Bodenheimer, and John Doyle
Abstract
This paper introduces an induced-norm formulation of a mixed H2
and Hinf performance criterion. It is shown that different mixed
H2 and Hinf norms arise from different assumptions on the
input signals. While most mixed norms can be expressed explicitly
using either transfer functions or state-space realizations of the
system, there are cases where the explicit formulas are very hard to
obtain. In the later cases, examples are given to show the intrinsic
nature and difficulty of the problem. Mixed norm robust performance
analysis under structured uncertainty is also considered in the paper
