一种复杂海况下舰载机着舰动态面控制方法

Given complex sea conditions, such as surges and hurricane weather, we design a carrier-based aircraft landing control system based on a dynamic surface controller and a nonlinear extended state observer. To compensate for the influence of complex disturbances such as airwake and deck motion on control accuracy, an extended state observer with a novel function of accumulated losses structure is designed, and the observed vector variation is introduced as the tracking error, which can effectively improve the hysteresis of disturbance observation and the slow convergence speed near the origin. To reduce the design complexity of the carrier-based aircraft control system and enhance control accuracy, a carrier-based aircraft landing control system based on dynamic surface control is designed to achieve decoupling between lateral control inputs. A homing pigeon-inspired optimization algorithm is proposed to achieve the tuning of controller parameters, and the algorithm's convergence is proved. Finally, the simulation results show that the carrier-based aircraft landing homing pigeon-inspired optimization—dynamic surface control system proposed in this paper is superior to the comparative landing control scheme, especially regarding landing accuracy and disturbance rejection.
