This research has been carried out to establish 1) guidance and control system of autonomous underwater vehicles (AUVs) in coastal waters and 2) design of configuration of AUVs in coastal waters for the purpose of development of global monitoring system of environment in coastal area by AUVs. This research deals with an autonomous underwater vehicle equipped with mechanical pectoral fins that has a high performance of attitude control under disturbances like water currents and surface waves in coastal waves.In the first year of this program, the optimization of the fin motion in terms of optimal control force generation was carried out using a mechanical fin system generating flapping motion, feathering motion and rowing motion. Kinematic studies indicate that pectoral fin motion of fish consists of drag-based mode at low speed and lift-based mode at high speed. The optimization found out that the lift-based rather than the drag-based swimming mode is suitable for generation of propuls … More ive force in uniform flow, while the drag-based rather than the lift-based swimming mode is suitable for generation of propulsive force in still water.In the second year of this program, the underwater vehicle equipped with two pairs of mechanical pectoral fins "PLATYPUS" was developed to assess the swimming performance and the control performance. We found that it has not only quite a good propulsive performance, showing the maximum speed of 0.64 m/s with lift-based swimming mode, but also a variety of maneuverability in hovering condition such as turning, descending and ascending, and lateral swimming. The task sharing by fore and aft pairs of mechanical pectoral fins enables a precise Point To Point control in 3-D underwater space that needs simultaneous performance of azimuth control, position control in horizontal plane and depth control. The drag-based swimming mode of the mechanical pectoral fin rather than the lift-based swimming mode is suitable for the motion control of the underwater vehicle that needs a prompt response under disturbances such as waves.

本研究旨在建立近海自主水下机器人(AUV)制导与控制系统和近海AUV构型设计，以开发AUV全球近海环境监测系统。研究了一种配备机械胸鳍的自主式水下机器人，该水下机器人在水流、海浪等扰动下具有高性能的姿态控制性能。在本项目的第一年，利用产生扑翼运动、羽化运动和划船运动的机械鳍系统，从最优控制力生成的角度对鳍运动进行了优化。运动学研究表明，鱼的胸鳍运动在低速时由拖曳模式和高速时的升力模式组成。优化发现，基于升力的游泳模式比基于阻力的游泳模式更适合于推进器…的生成在本项目的第二年，研制了配备两对机械胸鳍的水下机器人“鸭嘴兽”，以评估其游泳性能和控制性能。研究发现，它不仅具有较好的推进性能，在升力游泳模式下最大航速可达0.64m/S，而且在悬停状态下具有转弯、下降和上升、侧游等多种机动性。通过前后两对机械胸鳍的任务分担，实现了三维水下空间精确的点对点控制，需要同时完成方位控制、水平面位置控制和深度控制。机械胸鳍的阻力游动模式比升力游动模式更适合于在波浪等扰动下需要快速响应的水下机器人的运动控制。较少
