Research on fast track changing performance of carrier-based aircraft under DP mode

Carrier-based aircraft endow aircraft carriers with powerful combat capabilities but also bring about safety issues for carrier-based aircraft landing. Therefore, it is necessary to study the accuracy, speed and orbit-changing ability of carrier-based aircraft to follow ideal glide trajectories. Based on the control strategy of the US military's ‘magic carpet’ technology, with the E-2C as the target, decoupling the trajectory angle control and angle of attack control, a double-layer dynamic inverse landing flight trajectory incremental modal control method is designed. The simulation results show that the designed control law can accurately track the glide command, while maintaining the angle of attack and velocity, and has good control performance; provide the correction capability of carrier-based aircraft to correct back to −3.5° under different trajectory angle states, as well as the correction capability and boundary when there are different altitude deviations during the final landing phase.
