摘要:: 为了解决收放线过程中脱线、断线和张力不稳引起的切割表面毛刺的问题，该文以某切割设备有限公司的市场需求为背景，研究了开环张力控制算法以实现收放线的张力稳定。该算法根据卷筒直径与输出扭矩的比例关系，对电机输出的扭矩进行控制。通过材料厚度、圈数和比率计算的方式实现收放线卷径的计算。通过对设备加减速负载惯性力矩补偿，实现了加减速度阶段的张力稳定。该算法目前已经应用于某公司实际项目当中，系统经调试运行正常，完成了控制要求，达到了预期的控制目标，满足企业的切割需求。

Abstract:: In order to solve the problem of cutting surface burr caused by disconnection, disconnection and tension instability in the process of retracting and retracting wire, this paper studies the open-loop tension control algorithm to achieve tension stability of retracting wire based on the market demand of a cutting equipment company. The algorithm controls the output torque of the motor according to the proportional relationship between drum diameter and output torque. Through the material thickness, the number of turns and the ratio of the way to achieve the rewinding winding diameter calculation. By compensating the inertia moment of acceleration and deceleration load, the tension stability in the acceleration and deceleration phase is realized. The algorithm has been applied in a company’s actual project, the system runs normally after debugging, complete the control requirements, achieve the expected control objectives, and meet the cutting needs of enterprises.
