摘　　要：分析卷径测量对于卷绕系统中张力和线速度控制的意义,比较几种常见的卷径测量方法,利用编码器反馈信息、卷绕辊角速率及卷径累加模型,设计了一种基于递推最小二乘法的在线卷径估计方法,并在西门子SINAMICS运动控制平台上进行了验证。实验结果表明:该方法可以迅速准确地估算出当前卷径值和物料厚度,提高了工作效率,并为后续的进一步控制提供了可靠的数据支持。This paper analyzes the significance of reel radius measurement for tension and line speed control in reeling systems.It compares the characteristics of several common reel radius measurement methods and proposes an online reel radius estimation method based on recursive least squares,utilizing encoder feedback information,the angular velocity of the winding roller,and a cumulative reel radius model.The proposed method was experimentally validated on the Siemens SINAMICS motion control platform.Experimental results show that this method can rapidly and accurately estimate the real-time reel radius and material thickness,thereby enhancing work efficiency and providing reliable data support for subsequent control processes.
