悬停

Thus, by gradual development, the rotor jets (which had a high fuel consumption) were only used for take-off, hovering and landing, and the rotor blades turned by autorotation for forward flight in the manner of an autogyro.

因此，通过逐步发展，转子飞机仅用于起飞，悬停和着陆，并为着在地的旋翼飞行自动旋转转动转子叶片。

Gray reef sharks and red snappers hover above a patch of table coral, waiting for prey fish to emerge.

灰礁鲨，红笛鲷悬停以上补丁表珊瑚，等待猎物的鱼出现。

The sightline control strategy for bad measure precision is developed, and the control methods for vertical direction, approach direction and station keeping are presented.(2)The safe approach velocities are investigated for cuboid, sphere and cone keep out zone.(3)The design method for optimal trajectory under safety constraint is developed. The cone and cuboid keep out zone can be described using line constraint, and then optimal trajectory design can be translated to line programming problem under line constraint.(4) The design strategy of collision avoidance maneuver is discussed, and the collision avoidance scheme is analyzed for V-bar and R-bar approach.The control and trajectory safety in departure phase are investigated.

1提出了测量误差较大时平移靠拢段的视线控制策略，给出了横向、纵向和悬停的控制方法；(2)针对长方体禁区、球形禁区和锥形禁区三种禁区形式，研究了V-bar逼近和任意方向逼近的纵向安全速度计算问题；(3)提出了安全约束下的最优轨迹设计方法，将冲量和有限推力作用下的最优轨迹设计问题转化为线性规划问题，并给出了将锥形和方形安全区域约束转化为标准线性约束的公式；(4)探讨了紧急避撞机动的设计策略，分析了V-bar和R-bar接近的紧急避撞机动方案。

Based on the experiment platform of underwater vehicle control system made by ourselves, an underwater demonstration experiment system is developed with forward-looking cameras and man-made targets. Underwater demonstration experiments with the two station keeping methods are made in an indoor experimental pool.
