To overcome the characteristic of “backhoe”

reduce the burden of pilots control

and improve the accuracy and safety of carrier landing

the direct lift control method with the characteristics of quick response and high accuracy

is introduced into the carrier landing control law. A two-level integrated landing controller is designed with the combination of prescribed performance nonlinear dynamic inversion and control allocation algorithm

which considers the decoupling not only between longitudinal trajectory control and attitude control but (also) between horizontal control and longitudinal motion. Firstly

the 6-DoF nonlinear model of aircraft is established. Then the dynamic inverse loop is connected with the control allocation loop organically by setting the intermediate virtual control vector. Meanwhile

the control performance of the dynamic inverse control loop is improved by prescribing the error vector constraint equation. Finally

the simulation results show that the designed direct lift controller can adjust the vertical path while keeping the angle of attack and flight speed stable

and allow the aircraft keep the altitude while aligning with the center line. This study indicates that the designed direct lift control system can achieve a one-by-one correspondence between pilot maneuvers and control variables

improve the efficiency of trajectory control in carrier landing

and greatly reduce the burden of pilot.
