畢業(yè)設(shè)計(jì)的外文翻譯：橋式起重機(jī)的防搖和定位控制[外文翻譯]





摘要：近年來(lái)，很多學(xué)者對(duì)橋式起重機(jī)的防擺控制方法進(jìn)行了研究，以提高起重機(jī)的作業(yè)效率。針對(duì)起重機(jī)模型的非線性和不確定性，設(shè)計(jì)了一種基于模糊的起重機(jī)的定位和防擺控制方法，利用兩個(gè)模糊控制器對(duì)小車(chē)的位置和負(fù)載的擺動(dòng)分別進(jìn)行控制。其中，模糊位置控制器的設(shè)計(jì)是參考一個(gè)簡(jiǎn)單的速度參考曲線，對(duì)位置和速度進(jìn)行有效地控制；而模糊防擺控制器則模仿起重機(jī)操作員的實(shí)際操作經(jīng)驗(yàn)設(shè)計(jì)了一套模糊控制規(guī)則來(lái)消除負(fù)載的擺動(dòng)。仿真結(jié)果證明了該方法的可行性和良好性能，且該方法對(duì)不同的繩長(zhǎng)和負(fù)載有著較好的魯棒性。

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.
