Research and simulation on the carrier deck motion adaptive prediction for ACLS design

Proceedings of 2014 IEEE Chinese Guidance, Navigation and Control Conference, 2014
This paper focuses on the aircraft carrier deck movement prediction techniques which could be applied to the Autonomous Carrier Landing System (ACLS) design. The techniques introduced here are methods based on non-hydrodynamic, which is also called time series analysis algorithms. The algorithms based on AR model and ARMAX model are described in detail

A prediction method for deck-motion based on online least square support vector machine and genetic algorithm

Journal of Marine Science and Technology, 2018
The prediction accuracy and prediction time are key elements that determine the landing safety of the carrier-based aircraft when ship motions in six-degree freedom are difficult to restrain. The classical prediction methods, such as auto-regressive and moving average model (ARMA) and radical basis function neural network (RBF-NN), always suffer from ...

A prediction method for deck-motion of air-carrier based on PSO-KELM

2016 10th International Conference on Sensing Technology (ICST), 2016
Prediction for deck-motion is a practical measure to improve the landing/taking off safety of carrier-based aircraft when those deck-motions in six-degree freedoms cannot be effectively controlled/restrained. Deck-motions excited by waves and winds own characteristics of randomness and nonlinearity. It is generally believed those classical feed-forward
