Abstract
ABSTRACT The automatic carrier landing system (ACLS) is an indispensable component of modern aircraft carriers, and it can be considered a special cyber-physical system. However, the disturbance of the carrier air-wake in the final approach is detrimental to the landing safety and complicates the design of the ACLS. An air-wake rejection control strategy can be designed by analyzing the signal flow chart. To suppress the air-wake disturbance, the ACLS in this study is designed based on an adaptive backstepping sliding mode control. This design compensates and restrains the flight performance deviation, and it can also ensure the robustness of the system. Compared with the conventional ACLS design, the capability to restrain the flight performance deviation is significantly enhanced. The simulation results show that the system robustness is improved significantly. Moreover, the proposed design can achieve strict control of the ideal glide slope tracking and realize safe landing under the air conditions of the final approach.
