吊车稳钩控制系统的建模与仿真

Modeling and Simulation of Crane Hook Control System

起重机在运行过程中,随着各个机构的运行,容易引起重物朝着各个方向晃动,而这个晃动轻则引起运行的不稳定,严重时会引起安全问题。文章通过设计安装编码器,实时检测钢绳摆动的角度及钢绳的长度,建立稳钩控制系统的数学模型,通过MATLAB的仿真,获取了位置和角度曲线以及相关参数,为现场落实稳钩控制系统奠定了基础。

During the operation of the crane,with the operation of various mechanisms,it is easy to cause heavy objects to shake in all directions.However,this shaking may cause instability in operation,and may cause safety problems in severe cases.Through the design and installation of the encoder,the swing angle and length of steel rope were detected in real time,and the mathematical model of hook stabilization control system was established.Through MATLAB simulation,the position and angle curves and related parameters were obtained,which laid the foundation for the implementation of the stable hook control system on site.
