To achieve this, the tension control loop is utilized to regulate the tension in the unwinder module, and the velocity loop is utilized to regulate the web speed in the rewinder module owing to the limitation of the number of actuators. Moreover, the radius estimation algorithm is applied to achieve an accurate web speed and the control sequence of the web handling in the longitudinal axis is developed to manipulate the web handling for convenience. Having these, the tension control performances are validated within \u00b10.79, \u00b11.32 and \u00b11.58 percent tension tracking error and 1.6, 1.53 and 1.33 percent web speed error at the speeds of 0.1 m\/s, 0.2 m\/s, and 0.3 m\/s, respectively. The tension control performance is verified within \u00b10.3 N tracking error in the changes of the reference tension profile at 0.1 m\/s web speed. Lastly, the air floating roller is used to minimize the friction terms and the inertia of the idle roller in the tension zone so that tension control performance can be better achieved during web transportation.<\/jats:p>","DOI":"10.3390\/s22082917","type":"journal-article","created":{"date-parts":[[2022,4,12]],"date-time":"2022-04-12T22:48:45Z","timestamp":1649803725000},"page":"2917","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Experimental Validation of High Precision Web Handling for a Two-Actuator-Based Roll-to-Roll System"],"prefix":"10.3390","volume":"22","author":[{"given":"Jaeyoung","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Flexible and Printed Electronics, Korea Institute of Machinery and Materials, Daejeon 34103, Korea"}]},{"given":"Kyungrok","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Flexible and Printed Electronics, Korea Institute of Machinery and Materials, Daejeon 34103, Korea"}]},{"given":"Hyunchang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Flexible and Printed Electronics, Korea Institute of Machinery and Materials, Daejeon 34103, Korea"}]},{"given":"Pyoungwon","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Flexible and Printed Electronics, Korea Institute of Machinery and Materials, Daejeon 34103, Korea"}]},{"given":"Seonghyun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Flexible and Printed Electronics, Korea Institute of Machinery and Materials, Daejeon 34103, Korea"}]},{"given":"Taikmin","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Flexible and Printed Electronics, Korea Institute of Machinery and Materials, Daejeon 34103, Korea"}]},{"given":"Dongwoo","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Flexible and Printed Electronics, Korea Institute of Machinery and Materials, Daejeon 34103, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,11]]},"reference":[{"key":"ref_1","unstructured":"Morse, J.
