Abstract
In view of the variable aerodynamic configuration of the morphing aircraft, the complex force and the violent changes of the dynamic parameters, the Firebee variable sweep angle morphing aircraft is taken as the research object, and a new six-degree-of-freedom (DoF) multi-rigid body dynamics model of the morphing aircraft is established based on the Newton-Euler method. Compared with the longitudinal model of the traditional aircraft, the additional force and additional torque are expressed in this model. Based on the principle of TS fuzzy control, the T-S fuzzy control model of the morphing aircraft is established. In the process of reducing the sweep angle from 60° to 15°, the longitudinal motion response of the aircraft caused by the morphing aircraft is simulated and analyzed. The simulation results show that the T-S fuzzy control model can effectively adapt to the nonlinear and time-varying characteristics of the dynamics model during the deformation process of the morphing aircraft. The T-S fuzzy control can better maintain the stability and dynamic response of the morphing aircraft during the morphing process.
