Abstract:To address the problems of deck motion and carrier air wake during the carrier landing, this paper proposes a landing control method based on the relative motion between the landing deck and aircraft using incremental nonlinear dynamic inversion. This paper explores the mathematical relationships between the relative glide angle and the absolute glide angle without ignoring pitch motion of landing deck based on the relative motion and the corresponding geometric relationship, so as to realize accurate tracking of ideal landing trajectory. The recently popular incremental dynamic inverse control technology is used to design the control law for the inner-loop, which gets rid of the excessive dependence on the model accuracy and improves the robustness by making use of the measurement information, and also reduces the computation load effectively. The simulation results demonstrate that the landing control method proposed in this paper can track the ideal landing trajectory accurately and reduce the impact of deck motion on the landing accuracy effectively. At the same time, the designed incremental nonlinear dynamic inverse control law has strong robustness.
