In this paper, we consider the problem of robustness optimization for infinite-dimensional systems with respect to a class of bounded feedback-control laws. Both unbounded inputs and perturbations are allowed, where the well-posedness of the abstract controlled perturbed system is guaranteed by specifying Pritchard-Salamon-type conditions on the system parameters. The solution of the problem is determined via a doubly parameterized weak algebraic Riccati equation.
