在这一章中,我们研究了Zermelo在水上和水下的一类导航问题。这些都是“最优控制”问题,描述了以下情况:一个物体(船或潜艇)在水流中朝着目标行进。如何控制物体的转向角度,使物体在最短的时间内到达目标位置?我们将研究一个简单的情况,其中水以恒定速度矢量(电流)流动。它还假定,对象的速度和它的转向角是恒定的。如果目标是一个凸集,则策梅罗问题可以用凸参数规划模型来表示。我们的目标是说明几个典型的情况下使用前面的结果。
In this chapter we study a class of navigation problems of Zermelo on the water and under the water. These are “optimal control” problems that describe the following situation: An object (a boat or a submarine) travels in a stream of water towards a target. How should the steering angle of the object be controlled, so that the object reaches the target in shortest time ? We will study a simple situation in which the water flows with a constant velocity vector (current). It is also assumed that the object’s speed and its steering angle are constant. If the target is a convex set, then Zermelo’s problems can be formulated as convex parametric programming models. Our objective is to illustrate several typical situations using the preceding results.
