Abstract
En 中文
• The open-loop control surface responses in an undisturbed flow field are analyzed to characterize the inherent dynamic behavior of the missile, providing a foundation for subsequent control system design. • A prior-model-based disturbance rejection control scheme (NAMA-ADRC) is proposed, providing accurate inner-loop decoupling and strong robustness against nonlinear aerodynamic disturbances. • Within the multiphysics coupling framework, the proposed control strategy generates smooth control commands, reducing mesh distortion and improving the efficiency and accuracy of CFD simulations.
