Performance robustness with multiple objectives of linear control systems having structured norm-bounded uncertainty is considered. In order to deal with any two objective functions Ψ1 and Ψ2 associated with a single feedback control system, the combined criterion Ψ[Ψ1 ψ2]Ψ {slanted equal to or less-than}S 1 is often used. The paper, however, considers Ψ ψ1 Ψ ≤ 1 and Ψ W, 11 ≤ 1 directly. It is shown that it is possible to assess robust performance of two objectives by a single μ test if repeated nonscalar blocks are adequately introduced in the structure of μ. In other words, a performance robustness problem with multiple objectives is proved to be equivalent to a stability robustness problem with extra repeated uncertainty blocks. This equivalence theorem is applicable to various system and norm setups including sampled-data systems.
