    Abstract
    In response to carrier motion and ship wake turbulence during landing, this paper proposes an MPC-LQG (Model Predictive Control - Linear Quadratic Gaussian) algorithm for precision landing control of aircraft in the longitudinal path. First, key modules such as aircraft longitudinal motion, ideal touchdown point (ITP), ship wake, and landing guidance trajectory are modeled and analyzed. After that, the MPC-LQG algorithm for trajectory tracking control is proposed. The algorithm's main concepts are model predictive control for carrier motion compensation and the design of full-dimensional state observation to complete full state feed-back to achieve optimal landing control. Finally, a simulated implementation of the approach for a typical landing problem is carried out. The simulation results show that the algorithm performs well in terms of trajectory tracking, with an altitude deviation of 0.1–0.2 m at ITP.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
