Modeling, robust controller design and control surface allocation optimization for fighters

This study aims to develop a highly realistic dynamic model of fighter aircraft, which serves as the basis for dynamic modeling, flight controller design, control surface allocation algorithms, and trim system construction. These outcomes offer both theoretical rigor and practical technical support for aircraft control and stability. The study involves comprehensive dynamic modeling, integrating aerodynamic and engine models, ensuring accuracy and reliability through strict validation. This foundation supports the design of a robust flight controller, which maintains stability across various flight conditions and incorporates an innovative control surface allocation optimization. Additionally, the research highlights the importance of initial aircraft trimming and has developed a trim system to ensure stability during the initial phase, enhancing controllability. In summary, the research provides detailed dynamic modeling and the associated robust control design, setting the stage for high-fidelity fighter simulators, with significant implications for aircraft aggressive maneuver control and flight training efficiency. High-fidelity flight simulations, based on the public NASA’s F-16 fighter aerodynamic information, are conducted to verify the feasibility of the developed control framework.
