Self-scheduled and structured H⋡ synthesis : A launch vehicle application

This paper presents a new application of structured H
_∞
synthesis to tune self-scheduled controllers. Newly available MATLAB-based tools allow to tune fixed-structure linear controllers while satisfying H
_∞
constraints. Moreover multi-model synthesis capabilities can extend their application to self-scheduled controllers. This technique is successfully applied to the attitude control of a launch vehicle in atmospheric ascent phase.
