Abstract：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.
