Mixed H2/H∞ sub-optimization approach for integrated aircraft/controller design

Abstract

This paper presents a new methodology to solve the optimization problem of integrated aircraft/dynamic output-feedback controller design where both polytopic model uncertainties and multi-missions are considered. This design optimization is based on mixed H2/H∞ performance requirement. According to the projection lemma, the integrated design optimization problem is separated into aircraft parameter optimization problem and controller optimization problem. an LMI-based sub-optimization approach is proposed for the aircraft parameter design. Then for the obtained sub-optimal aircraft parameters, an optimization approach is given to solve for the dynamic output-feedback controllers corresponding to different missions.
