英文摘要： According to the rotary structural characteristics and multi-task configuration requirements of the shuttle for deep-sea space stations，the performance of the networked control system and the quality of network transmission are investigated. The main contents are as follows: ①With the consideration of overall structure and multi-rudder layout, the vector control approach is investigated for networked control system of the rotary shuttle,the Lyapunov equation and dicrete-time Riccati equation are used to analyze its stability, to enhance its precision in spacial location and orientation. ②According to the requirements of multi-task and field configuration, and the characteristics of module node transmissions in the shuttle, the multi-agent and intelligent searches are used to get dynamic balance transmission scheduling arithemic, in order to strengthen the communication scheduling adaptability under different configurations. ③Aiming at different precision requirements in different navigation stages, the Gradient Descent Arithemic(GDA) and the Weighting Function Arithemic(WFA) are used to comprehensively optimize the control and transmission, in order that the shuttle can meet the different control performance requirements during shultting among the space stations, and coming in or out the space stations.
