Li-ion Battery Electrode Manufacturing Control System in Winding Process: Tension Control in Industrial Complex Roll-to-roll Winding Machine via SMC-FLC Hybrid Control Method

Abstract

This article introduces a new control method for web tension control on a complex roll-to-roll winding machine used in battery production. Traditional web tension control method cannot perform well enough under high winding speed: the parameter tuning process is time-consuming, and the disturbance rejection performance is not satisfying, and the control performance is not stable. A hybrid control method is proposed, and it is easy to be implemented on common programming platform for commercial winding machines with an easy tuning process, while providing superior control performance to traditional control method. The system modeling used in the control method is much simpler than the modeling in most of tension control research, providing better feasibility for industrial application.
