Structured perturbations are easy to use to create perturbed plants: simply pick values for $e_m$, $e_b$, and $e_k$ that are within the allowable bounds and plug them in to create a new, perturbed transfer function. -Structured perturbations allow for sampling of the set, but they do have a significant drawback. Structured perturbations severely restrict - Structured perturbations do suffer from a limit (The disk multiplicative perturbation)
