Center Position Control for Steel Machine Using Electro-Hydraulic Actuator

다국어 초록 (Multilingual Abstract)

This paper presents an application of electro-hydraulic actuator (EHA) to a steel rolling machine (SRM) in order to control the center position of the roller which affects directly to the working performance. The EHA control system is developed from a conventional servo hydraulic actuator (SHA) which is currently used to control the roller center of the SRM in POSCO Corp. Based on the EHA specifications and control requirements, the EHA circuit and its components are designed. In addition, the ability of using EHA for center position control (CPC) is verified by force control performance on an electro-hydraulic test machine (EHTM) in which the reference is the working data obtained from the SHA. Experimental result proves that the EHA has strong potential to be applied for CPC of the SRM.
