Abstract:This paper proposes a landing control system based on incremental dynamic inverse control . The control system consists of an angle of attack maintenance loop and a trajectory rate control loop based on incremental dynamic inversion, which achieve decoupling of angle of attack and trajectory, as well as direct control of trajectory by direct lift. A differential tracker is introduced to estimate the track angular acceleration signal required in the incremental dynamic inverse control law. The simulation results show that the designed landing control system based on incremental dynamic inversion has excellent control accuracy, speed, and robustness. It can achieve accurate tracking of the trajectory under different sea conditions interference, and the landing points can meet the quality requirements for the distribution of carrier based aircraft landing points.
