毕业设计的外文翻译：桥式起重机的防摇和定位控制[外文翻译]
摘要：近年来，很多学者对桥式起重机的防摆控制方法进行了研究，以提高起重机的作业效率。针对起重机模型的非线性和不确定性，设计了一种基于模糊的起重机的定位和防摆控制方法，利用两个模糊控制器对小车的位置和负载的摆动分别进行控制。其中，模糊位置控制器的设计是参考一个简单的速度参考曲线，对位置和速度进行有效地控制；而模糊防摆控制器则模仿起重机操作员的实际操作经验设计了一套模糊控制规则来消除负载的摆动。仿真结果证明了该方法的可行性和良好性能，且该方法对不同的绳长和负载有着较好的鲁棒性。
关键词：桥式起重机；定位和防摆控制；模糊控制；稳定性分析。

Anti-swing and positioning control of overhead traveling crane
Jianqiang Yi, Guangxun Tian
Abstract: Recently, many approaches have been implemented for anti-swing control of overhead crane in order to improve the operational efficiency. It is proposed a fuzzy logic-based anti-swing and position control of overhead cranes considering the nonlinearity and uncertainty of the crane model, where two fuzzy controllers are designed to control the trolley position and to load swing separately. The fuzzy position controller is based on a simple speed reference trajectory to control the position and velocity of the trolley; and in the fuzzy anti-swing controller, the fuzzy rules are devised to resemble the experience of human crane operators for eliminating the load swing. Simulation results verify the feasibility and good performance of the method, and robust to different rope length and load mass.
Keywords: bridge crane; anti-swing and position control; fuzzy control; stability analysis.
1. Introduction
Overhead traveling crane plays an important role in many factories, which transports a load from one place to another. Because high positioning accuracy, small swing angle, short transportation time, and high safety are required, operating an overhead traveling crane is a hard work and automation of operation is desirable.
