This paper presents an application of an electro-hydraulic actuator (EHA) and a novel control method - online tuning modified-Grey fuzzy PID controller (OTMGFPID) to a steel rolling machine (SRM) in POSCO Corp. in order to improve its working performance. In this SRM, the center position of the roller, which affects directly the rolling quality, is controlled by the EHA system instead of using a conventional...
This paper presents the lateral position control of a moving web using a steering guide system in roll-to-roll (R2R) printed electronics. In typical R2R printed electronics processes, a web like plastic film runs through a long drying section where the lateral displacement of web is affected by the airflow in the dryer. In order to eliminate the lateral error, a steering guide can be used. We developed...
