摘要
起重机的摆动会降低装卸效率,影响运输安全。传统的电子控摇系统采用力控制方式,推导繁琐,计算量大。采用速度控制方式,通过控制小车的加速度来控制吊重摆动,所建立的模型不损害系统的非线性特性,且计算相对简单。具体实施过程中,建立闭环控摇系统,对系统输入、传输和外界作用等引起的误差进行修正。系统输入由编制的PLC程序实现。实验证明,这种方法直接、简单,可以有效控制吊重摆动,达到理想的控摇效果。
The sway of the load happened during the move-ment of the trolley is harmful to the crane's discharge and safe-ty. Tranditional electronic sway control system adopts force-con-trol mode, which needs a great deal calculation. This paper ap-plies speed-control mode to the sway control system. No lin-earization and simplification have made. It sets up a close loop control system, which modifies the error caused by the input, transmission and outside disturbance. The input is achieved by PLC. The experiment shows that it is simple and effective.
