摘　　要：需要对链式自动机闩体进行精确定位控制,以确保能够在射击结束时完成抽壳并能在确定的位置点进行供弹和弹种转换操作。提出了一种基于电机旋变的增量式位置控制器设计。通过射长、传动减速比计算绝对位置主令,通过圈数特征和旋变位置确定位置反馈,实现位置闭环控制。提出一种射长不定的特殊情况下,位置主令的计算方法。通过对位置控制环开环传递函数分析,实现高精度定位控制。研制了一套自动机驱动控制系统作为实验平台,试验结果表明,能够有效实现高精度闩体位置控制。Due to its own structure and safety requirements,chain automata require precise positioning control of its bolt body to ensure that it can complete shell extraction at the end of shooting and perform ammunition feeding and tank type conversion operations at the determined position points.A design of an incremental position controller based on motor rotation is proposed to meet the precise positioning requirements of chain automata.Calculate the absolute position master command through shooting length and transmission reduction ratio,and determine the position through the number of turns feature and rotation position feedback has achieved closed-loop control of position,and a calculation method for position command has been proposed in special cases with uncertain shooting length.By analyzing the open-loop transfer function of the position control loop,high-precision positioning control can be achieved.Finally,a set of automatic machine drive control system was developed as an experimental platform,and the experimental results showed that this method can effectively achieve high-precision latch body position control.
