An idea of applying μ-synthesis to launcher attitude and vibration control design

This paper presents a methodology for applying mu-synthesis to a real high-order system: launch vehicle attitude and vibration control. The design involves robust characteristics against uncertainties of the system parameters as well as precise tracking performance under limited rigidity. As the plant dynamics has an extremely high order and unstable character, the standard mu-synthesis cannot be directly applied. Thus, the standard procedure is modified in a special way in order to make the approach more efficient. The methodology provided in the study will contribute to a better understanding of how to apply the robust control theory to complicated real problems.
