摘　　要：机床传动环节的反向间隙是影响半闭环数控机床定位精度最主要因素之一,为补偿反向间隙的影响,提出了一种基于加减速控制的反向间隙补偿方法,该方法可在满足执行电机动态性能要求的同时,实现最短的反向间隙补偿时间。最后将该方法应用于机床伺服轴上,实验结果表明,该方法可有效补偿伺服轴传动环节所产生的反向间隙。Backlash of the transfer motion link is a primary factor for the positioning accuracy of machine tools. To compensate for the effect of backlash, a method based on acceleration and deceleration control was presented. It can satisfy the limit of motor dynamic performance, and fulfill the shortest backlash compensation time. When the method was applied on the machine tool servo axis, the experiment result shows it can compensate for the backlash effectively.
