Unmanned surface vehicle (USV) has huge military and engineering applications and will play an irreplaceable role especially in maintaining national maritime safety and marine development. Therefore, USV has become a research hotspot at home and abroad. In this paper USV motion control is studied from the view points of entire drive control and underactuated control respectively. Main research achievements at home and abroad are expounded. Underactuated control mainly includes: stabilization control, trajectory tracking and path following. Main problems existing in USV motion control methods are summarized, and research direction in the future is prospected.%无人艇具有巨大的军事和工程应用前景，尤其是在维护国家海洋安全和海洋开发等方面将发挥不可替代的作用。因此无人艇日益成为了国内外的研究热点，其中无人艇的运动控制技术是实现其工程应用的基础。文中针对无人艇的运动控制问题，从全驱动控制和欠驱动控制角度，分别阐述了国内外主要研究成果，其中欠驱动控制主要包括：镇定控制、轨迹跟踪和路径跟踪三个方面。总结了无人艇运动控制方法目前存在的主要问题，并对未来的研究方向进行了展望。
