Design of an adaptive tension/velocity controller for winding processes

摘要

In a winding process, important control specifications include regulation of web tension and velocity. In this research, an adaptive tension/velocity controller has been developed for winding processes. For the controller design, the linear quadratic regulator theory has been adopted and a gain-scheduling scheme has been incorporated. A prototype winding system has been constructed, and the controller has been implemented in a real-time PC-based environment. The performance of the closed loop system has been evaluated via simulation and experiments, and it was observed that both the web tension and velocity could be regulated within a small tolerance.
