By taking carrier based aircraft as the studying object, we set up the dynamic model and design a carrier based aircraft automatic landing control system based on the H2 full information preview controller, which can suppress the interference caused by carrier air wake movement and track the landing glide slope. Taking a certain type of carrier based aircraft as the controlled object, a non linear numerical simulation is made. The results show that: 1) the H2 full information preview control strategy can improve the effect of rejecting air wake interference, obtain a quicker system response and a satisfactory trajectory tracking effect;and 2) the control effect is better than that of PID control.
