摘　　要：桥式起重机作为港口重要装卸工具,影响装卸效率的关键因素是桥式起重机的防摇技术。本文针对防摇控制的问题,将桥式起重机运行系统作为研究对象,通过运行机理建立了数学模型,计算分析桥式起重机防摇控制的影响因素,设计了相应的智能防摇控制系统,进行了对比试验,模糊控制更适合起重机防摇控制,该策略以小车实际输出位置与参考位置之差作为控制量,同时将负载的摆角也作为控制量,形成双闭环控制。通过仿真对比分析,可以实现对小车位置和负载摆角的有效控制,达到在有限时间内快速稳定的控制要求。As an important loading and unloading tool in ports,the key factor affecting loading and unloading efficiency is the anti roll technology of bridge cranes.This article focuses on the issue of anti roll control and takes the operating system of bridge cranes as the research object.A mathematical model is established through the operating mechanism,and the influencing factors of anti roll control of bridge cranes are calculated and analyzed.A corresponding intelligent anti roll control system is designed,and comparative experiments are conducted.Fuzzy control is more suitable for anti roll control of cranes.This strategy uses the difference between the actual output position of the trolley and the reference position as the control variable,At the same time,the swing angle of the load is also used as a control variable to form a dual closed-loop control.Through simulation and comparative analysis,effective control of the position and load swing angle of the car can be achieved,achieving fast and stable control requirements within a limited time.
