吊车系统的状态反馈控制的极点配置法

STATE FEEDBACK CONTROL OF AN OVERHEAD CRANE BY POLE PLACEMENT

本文以带重物的吊车系统为对象 ,在尽量使重物不偏离垂直方向的同时 ,也要使吊车在水平方向保持某一基准位置 ,这是一个研究向吊车施加水平方向力的多输出控制系统的设计问题 .文章通过状态反馈利用极点配置法找到一个控制力u ,使得整个吊车系统达到稳定 。

We are interested in an overhead crane, carrying the paylead. Not only does the rope angle approximately attain zero but also the trolley position varies small is our experct. It is a controller design problem on multi-output system when a force u is applied to the trolley. A methodlogy is proposed to control the transient sway and residual oscillation of a paylead carried by an overhead crane. The design approach is based on state feedback by pole placement. It would be quite feasible to be applied to standard industrial control systems.
