摘　　要：为了保证变构型飞行器变形过程中的姿态稳定,针对具有非线性、强耦合和外部干扰的变构型飞行器姿态动力学模型,给出一种基于增量非线性动态逆的姿态控制方案。使用非线性动态逆的思想,设计增量非线性动态逆控制器,并结合扩张状态观测器补偿外界干扰。通过数值仿真,验证了基于增量非线性动态逆的飞行器姿态控制方案的有效性。仿真结果表明,设计的增量非线性动态逆控制器能够保证变构型飞行器变形过程中的姿态控制性能。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.
