This problem is reducible to a two- or one-block H∞ control problem with structured weighting functions. We first show that these weighting functions violate the genericity assumptions of existing Hamiltonian-based solutions such as the well-known Zhou-Khargonekar formula. Then, we derive a new closed form formula for the computation of the optimal performance level, when the underlying plant structure is specified by a pseudorational transfer function.EnglishH∞ controlInfinite-dimensional systemsMixed sensitivity optimizationPseudorational transfer functionSkew-Toeplitz approachComputational methodsControl systemsHamiltoniansOptimizationProblem solvingH^∞ controlInfinite-dimensional systemsMixed sensitivity optimizationSkew-Toeplitz approachSensitivity analysisArticle10.1016/j.sysconle.2005.03.002
