Abstract: | LetP(y,M) be a family of polynomials, depending on a controller parameter vector y in
n+1, defined as follows: a family of interval matrices, and y in
n+1, set Given an initial stabilizing controller y0, this paper provides a simple method to robustify y0, i.e., to obtain a controller parameter vector y1 which is more robust than y0. Furthermore we define the stability factort for a given robustly stable controller y, which serves as a measure of the robustness of y. |
