UC知道小弟是学机械的，毕业设计搞起重机吊臂，有一段英文急需翻译，望各位高手多加帮忙。

原文如下：A particularly important case is that of ship-mounted cranes. These are boom cranes mounted on see-going vessels and used to transfer cargo from larger cargo ships to lighter port-going vessels. Wave-induced motions of the ship produce base excitations at the boom tip, thereby subjecting the payload to pendulations. As the sea state rises, these pendulations increase. In high seas, cargo transfer has to be suspended due to payload motions reaching unsafe levels. This constraint on ship-mounted crane operations leads to time delays in shipping flow and cost overruns [1].
Several control strategies were proposed to reduce payload pendulations in the absence of base excitations. Sakawa et al. [2] proposed an optimization scheme to generate the torque
profile necessary to transfer a load along a predefined path while minimizing the payload pendulations during transfer and at the target point. The transfer time is minimized by iteration.
The technique was applied to a

特别重要案件是那运输登上的起重机。 这些是登上在看见去的船和使用的景气起重机从更大的货船转移货物到更轻的口岸去的船。 船产物基地励磁的挥动导致的行动在景气打翻， 从而服从酬载对pendulations。 海洋状况上升， 这些pendulations增量。在公海， 货物调动必须暂停的归结于到达不安全的水平的酬载行动。 这个限制在运输登上的起重机操作在运输流程和费用超限
几个控制战略提议在没有基本的励磁时减少酬载pendulations。 Sakawa等。 [2]提出优化计划引起扭矩外形必要转移装载沿一个被预定义的道路，当使酬载pendulations减到最小在调动期间时，并且在目标指向。 传送时间由叠代减到最小技术被申请了于旋转在一个恒定的逆风行驶角度的景气起重机的一个被模仿的模型，当卷在缆绳时并且在酬载平衡位置附近线性化了。 模仿结果表示，酬载免于残余的pendulations在目标点， 然而，当旋转角度增加，酬载pendulations沿道路开发并且增加。
