目前,集装箱港口作业多采用单箱操作,大大影响了港口的作业效率。文章根据双吊具的操作原理,在双电机传动试验平台的基础上,建立了异步电机矢量控制的Si mulink仿真模型,在Simulink仿真的基础上,提出了半闭环位置跟踪控制系统方法 ,实验结果表明,无论是正常状况还是干扰作用下,电机2均能可靠跟踪电机1的运动,两者同步误差较小,达到了较好的同步效果。
At present, the container port operations using more than one box operation, greatly affected the operational efficiency of the port. Based on the operation principle of double spreader, based on the double motor drive test platform, the Si mulink simulation model of asynchronous motor vector control is established. Based on Simulink simulation, the semi-closed loop position tracking control system is proposed. The experimental results It shows that the motor 2 can track the movement of the motor 1 both in normal condition and in the interference condition, and the synchronization error between the two is small, which achieves a better synchronization effect.
