Research on Tension Control of Winding Systems Using Electronic CAM

Abstract

Tension control is a crucial technology for winding control. In the present work, a theoretical analysis and design of tension control used in the winding systems for lithium-ion battery is proposed. Through analyzing the winding process of battery batteries, a speed control curve of the winding motor is designed, with which we can achieve a constant-linear-speed operation of the pole-pieces. Based on the electronic CAM technology, using the approximation method, the constant-linear-speed control curve is obtained. Experimental work is done to study the actual evolution curve of speed for battery pole-pieces. Experimental results show that the rate of speed fluctuation between the maximum speed and the minimum speed reduces from about 10 times to 2 times. It confirms the effectiveness of the application of electronic CAM control strategy in tension control.
