绳长对起重机载荷消摆影响的计算机仿真

The Computer Simulation of the Influence on the Anti-Sway Control of Cranes with Changing Rope-Length

对于断续控制的起重机载荷消摆，在绳长不变的情况下，作者已提出了基本时间最优的两拍消摆策略。本文进一步分析了绳长变化对这一消摆策略的影响，通过计算机仿真得出了当实际绳长大于设定值时具有较好鲁棒性的结论，为消摆控制器的设计提供了依据。

The author put forward a two-beat anti-sway methodology for intermittent cranes,taking rope-length as a constance.This paper discusses the influence of the changing rope-length on this methodology.By simulation on computer,it is concluded that there is a better robustness when the actual rope-length is longer than given value.It offered a evidence for design the crane anti_sway controller.
