Direct Lift Carrier Landing Control Based on Adaptive Nonlinear Dynamic Inversion for Carrier-Based Aircraft

To address the challenge of precise landing of carrier-based early warning aircraft under the influence of carrier air wake and deck motion, this paper proposes a direct lift landing control approach founded on adaptive dynamic inversion. The angle of attack stabilization channel and trajectory control channel were designed using adaptive dynamic inversion to achieve decoupling between the angle of attack and track angle. The stability of the landing controller was proved in the sense of Lyapunov stability. A simulation was conducted on the direct lift landing control system design, taking into account the influence of the carrier air wake and deck motion. The simulation demonstrates that the designed landing control system has the ability to weaken the interference between the carrier air wake and deck motion, achieve constant maintenance of angle of attack and precise tracking of the flight paths, and has excellent control accuracy and robustness. Overall, the performance of Control system can meet the landing quality requirements.
