With the rapid development of intelligent technology, the technology in the field of unmanned surface vehicles (USV) control is gradually improving, and the manual mode plays a vital role in the navigation safety of USV. In this paper, the fault tolerance of data transmission is improved by adopting three-linear interpolation technology in attitude data feedback, and the speed of unmanned ships is controlled based on PID control technology, and finally the construction method is verified through real ship experiments, which can provide theoretical support for future unmanned ship control systems.
