Abstract :
We summarize a new method for the computation of an L2 robust performance norm for systems perturbed by multiple linear time-invariant scalar perturbations. The method is based on replacing the perturbations with a parametrized set of finite-dimensional systems that can cover the same phase values as the original set of perturbations. The computations are reduced to ensuring that the elements of a linearly parametrized set of Hamiltonian matrices have no purely imaginary eigenvalues
