Integrated design of aerodynamics and control system for Micro Air Vehicles

Technology on Micro Air Vehicles (MAVs) has been attracting the attention for aircraft's researchers. Multidisciplinary optimization is expected to achieve the higher performances and the stability for MAVs. This paper proposes the simultaneous optimization methods of the aerodynamics based on the aircraft shape and the control system. The purpose of the optimization is to reduce the control energy and the roll angle under the constraints with respect to the robust stability. The control system is composed of the H-2 and the mixed H-2/H-infinity controllers. Efficient optimization procedures based on a two step procedure for the H-2 optimization and LMI solver for the H-2/H-infinity, control are developed in this study. Both aircraft shape and control design variables are simultaneously optimized by the proposed methods. Effectiveness of the proposed approaches is verified with some numerical applications.
