Adaptive Control of Web Guides Conference Paper uri icon


  • The focus of this paper is on the design and implementation of an adaptive algorithm for control of two common intermediate web guides used in the roll-to-roll manufacture of webs. Web guides are used to control the lateral position of the web on rollers in RTR processing of flexible materials (webs). We consider the design of a model reference adaptive controller for web guides. The feedback for this adaptive control system is the web edge position. The emphasis is on practical implementation issues such as selection of design parameters and improving the robustness of conventional adaptive control schemes. We consider modifications of the conventional model reference adaptive controller for it to provide improved performance for the web guiding application.We show via extensive experimentation that the designed model reference adaptive controller can provide much improved guiding performance in the presence of material variations and disturbances. We also compare the performance of the adaptive controller with an often used industrial PI control scheme. A representative sample of the experimental results are shown and discussed. 2011 IFAC.
