electrical engineering, information and communication engineering, control science, and engineering. The research platform is mainly used to overcome the problems of marine scientific research and shipping science and technology, serve the construction of \"double first-class\", actively build a research base for high-tech ships in the era of artificial intelligence, provide strong scientific and technological support for the construction of a strong maritime nation, and cultivate high-quality shipping talents. When the ship is operating at sea, the wind, waves, and currents on the sea surface have a great influence on the interference load generated by the ship; in order to better achieve the intelligent research and training dual-purpose ship's \"intelligent research + student teaching and training\" function, the reliability of the ship and control accuracy has higher requirements. In this paper, on the basis of the previous research on ship power positioning, we take the \"intelligent research and training dual-use ship\" as the research object, calculate the hydrodynamic derivatives, calculate the M inertia coefficient matrix and D damping coefficient matrix, derive the ship's three-degree-of-freedom model, and bring the model to the linear sliding mode and the terminal sliding mode controller for simulation. Dynamic positioning system (DPS) is a technology that uses ship propellers and control systems to keep ships in a fixed position or on a predetermined course at sea. DPS has a wide range of applications in ocean engineering, offshore operations, and maritime rescue. Although DPS has been explored in existing studies such as [PERSON], K, 2022 [1], there still exist gaps such as the study being on modeled or non-intelligent ships, and there are many limitations to the study, which this study aims to fill. The current DPS has some problems, such as low control accuracy, high energy consumption, and sensitivity to environmental interference. In order to solve these problems and improve the performance and reliability of DPS, more in-depth theoretical research and experimental verification are needed. Taking the intelligent research and training dual-use ship of Dalian Maritime University as the object of study, research on ship DPS control was carried out. On the one hand, it can promote the innovation and development of intelligent ship technology, explore and verify more efficient, stable, and energy-saving DPS control algorithms, improve the control accuracy and adaptability of DPS, reduce the energy consumption and environmental impact of DPS, and provide theoretical support and experimental basis for the innovation and development of intelligent ship technology. On the other hand, it can enhance the ability and level of ship intelligent research and experimentation, build a ship intelligent research and experimentation verification platform, conduct research on intelligent navigation technology and system, ship remote monitoring, shore-based support, ship intelligent communication technology, ship intelligent operation and maintenance technology, and other aspects, carry out collaborative research with other intelligent ships, explore the collective behavior and collaborative control of intelligent ships, and enhance China's international influence and competitiveness in the field of intelligent ships. In addition, it can also cultivate high-level talents in the field of intelligent ships, be used to train intelligent shipping talents, serve students' cognitive learning, practical training, and intelligent training, enable students to come into contact with the most advanced intelligent ship equipment and systems and master the basic principles and operation methods of intelligent ships, cultivate students' innovative thinking and practical ability, and cultivate professional talents for the application and development of DPS. Secondly, research on actual ships has many advantages over research on model ships.
