Lateral flight control design for a highly flexible aircraft using nonsmooth optimization

This paper describes a nonsmooth optimization technique allowing to design a lateral flight control law for a highly flexible aircraft. Flexible modes and high-dimensional models pose a major challenge to modern control design tools. It is shown that the nonsmooth approach offers potent and flexible alternatives in this difficult context. More specifically, the proposed technique is used to achieve a mix of frequency domain as well as time-domain requirements for a set of different load conditions.
