Robust stability of a linear multivariable system, in the sense of robustness under multiplicative transfer function perturbation, is necessarily preserved under sufficiently small perturbations in the model parameters (i.e. it is a robust property). In this paper, parameter perturbation bounds ensuring the persistence of the robust stability property are derived.
