Advanced hinf synthesis for launch vehicle attitude control in atmospheric flight

This paper discusses the use of a hybrid genetic-algorithm/structured H-Infinity technique for the synthesis of the attitude controller of a launch vehicle in atmospheric flight, that guarantees performance while satisfying a set of robustness/stability requirements typical of the industrial practice. The procedure is mostly automated, allows to deliver a gain-scheduling controller at an arbitrary number of points without requiring the designer a significant effort, and it is thus especially suited to reduce the missionisation burden.
