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.
