This paper deals with μ-synthesis of an electromagnetic suspension system using H_∝DIA control. H_∝DIA control is an H_∝ controls problem which treats a mixed Disturbance and an Initial-state uncertainty Attenuation (DIA) and supplies H_∝ controls with good transients. D-K iteration is well-known as one of practical approaches for the μ-synthesis problem. It is a heuristic iteration constructed with a calculation of D matrix based on μ-analysis and a calculation of a controller K(s) by the H_∝ synthesis. We propose a modified D-K iteration approach with the H_∝DIA control for the μ-synthesis problem in order to achieve both the robust performance condition and the H_∝DIA condition for good transient responses. We apply this proposed approach to an electromagnetic suspension system, and evaluate both robust performance and transient resonse via several experiments.
