摘　　要：针对高架门机自升过程中出现的振荡现象，文章建立了控制系统数学模型。通过对模型的仿真分析，再现了实际顶升过程中的振荡现象。分析了产生振荡现象的原因，提出了消除振荡现象的一些可行措施。This paper analyzed the oscillation of the crane,which has a high center of gravity. A mathematical model of the control system was established,the oscillation of the crane occurring in practical lifting was repeated,and several useful measures were proposed.
