In order to ensure the attitude stability of morphing aircraft in the deformation process,an incremental nonlinear dynamic inversion based attitude control scheme is proposed for the attitude dynamics model of morphing aircraft with nonlinear,strong coupling and external disturbance.The incremental nonlinear dynamic inversion controller is designed based on the idea of nonlinear dynamic inversion,and the external disturbance is compensated by combining the extended state observer.The effectiveness of the aircraft attitude control scheme based on incremental nonlinear dynamic inversion is verified by numerical simulation.The simulation results show that the designed incremental nonlinear dynamic inversion controller can ensure the attitude control performance of morphing aircraft during deformation.
