Abstract :
In this paper, we develop bounds for the H2 performance of systems with uncertainty, yielding a mixed H2/μ performance criterion. Using results from dissipation theory, we show how the μ upper bounds can be derived in terms of dissipation inequalities. This framework is extended to include an H2 performance metric to produce an overbound on the worst case H2 performance of a system with uncertainties. This work extends previous work in mixed H2/μ performance metrics by allowing nonequalised weights at both the input and the output, and by allowing multiple uncertainties
