An Status-deformation Cooperative Control for Morphing Vehicle

Morphing vehicles achieve optimal flight performance by changing shape under different flight conditions and missions to meet different mission requirements. In this paper, the variable span vehicle is studied, and the status-deformation cooperative control of the morphing vehicle is developed. The structural deformation of the vehicle is treated as the control input, and the status-deformation cooperative control model is established. Then, a virtual adaptive sliding mode control law is designed and assigned to the actual control inputs by solving the optimization problem. Simulations show that the control algorithm achieves status-deformation cooperative control, Compared to conventional vehicles, morphing vehicle can achieve desired cost function optimization by actively changing the wingspan at different flight phases, reducing fuel or rudder deflection requirements.
