Carrier based aircraft are in a low dynamic pressure state during landing, with static and unstable anti zone characteristics. In order to improve their flight quality, a power compensation system needs to be added. This article analyzes the three commonly used types of automatic throttle in power compensation systems and obtains the automatic throttle for magic carpet landing. Using a nonlinear dynamic inverse development method to design the incremental mode of the flight path and comparing with PID control. Simulation verification shows that NDI control has higher efficiency, better tracking effect and the designed automatic throttle can achieve good speed maintenance in two states: correcting back to the reference path at different trajectory angles and changing the landing trajectory.
