Abstract

In this paper, the robust controller design for a 3 MW boiler feed pump is presented. The dynamics of this pump are discussed, and a systematic way for transforming the robustness and performance requirements to the μ-synthesis setting is described. As the core of the paper, a new theorem for determining suitable uncertainty weighting functions for MIMO-problems is presented and applied to the AMB pump. The controller designed on this basis proves to meet the specifications
