摘要：
This paper proposed a deformation-aided altitude control strategy for the high aspect ratio aircraft to address the flight control problem of the structure/flight coupling dynamics. Based on the assumption of element wings, the dihedral deformation of high aspect ratio aircraft are constructed, and the structure/flight longitudinal coupling dynamic model is established. Two control strategies are discussed: altitude control with active morphing (AM) and passive morphing (PM). The elevator is regarded as the only control input in PM strategy, whereas control inputs are extended as elevator and torque in AM strategy. An identical linear quadratic regulator control method is adopted in both control strategies. Simulation results show that the AM strategy can effectively improve the transient processes of altitude tracking and reduce damping in the attitude channel. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
