Robust factor
WebThe problem of robustly stabilizing a family of linear systems is explicitly solved in the case where the family is characterized by H/sub infinity / bounded perturbations to the numerator and denominator of the normalized left coprime factorization of a nominal system. This problem can be reduced to a Nehari extension problem directly and gives an optimal … WebMay 12, 2024 · This means that the size of the robust z-scores is also comparable with the size of the standard z-scores, and quantiles from the normal distribution can be used, for …
