    Abstract
    The winding segmented permanent magnet linear synchronous motor (WS-PMLSM) generally adopts three-phase windings and the length of the segment is greater than that of the passive mover. This article proposes an innovative design for the module motor, using two-phase integrated single-layer concentric distributed windings, no half-filled slots, and the influence of the pulsating magnetic field generated by the segmented windings is negligible. By analyzing the transition of the segment winding, a variable parameter mathematical model is established, and proportional resonance (PR) control is introduced to eliminate the influence of parameter changes on the model. Meanwhile, the concept of a multiphase motor is introduced for pass-through segment control, with the help of the double $\alpha $ – $\beta $ coordinate transformation method, a new effective coil selection and switching algorithms is constructed, and the thrust forces for the pass-through section are obtained. It is experimentally confirmed that this design is in line with the production.

    • 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
