Abstract This paper proposes a new approach for multi-objective robust control. The approach extends the standard generalized l2(Gl2) and generalized H2(GH2) conditions to a set of new linear matrix inequality (LMI) constraints based on a new stability condition. A technique for variable parameterization is introduced to the multi-objective control problem to preserve the linearity of the synthesis variables. Consequently, the multi-channel multi-objective mixed Gl2/GH2control problem can be solved less conservatively using computationally tractable algorithms developed in the paper.
