The variable-sweep-wing morphing waverider is a promising solution for the wide speed range flight with adaptability to various mission requirements. However, it is a highly nonlinear system with inherent uncertainties and complex internal couplings due to the alteration of its configuration. In this paper, a dynamic and kinematical model with explicit expression of nonlinear/coupled forces and moments caused by morphing is proposed in a six degree of freedom flight. However, the above morphing forces and moments are difficult to measure and they can be estimated by the designed nonlinear disturbance observer. Then, a nonlinear model predictive controller is developed based on the state space model considering estimated disturbances. The global asymptotic stability of the composite controller can be guaranteed through stability analysis. Lateral weaving numerical simulation cases of the morphing waverider are carried out to investigate lateral maneuverability and overall controller performance.
