In industrial manufacturing systems, situations are often encounters in which motion with two, three or more hydraulic cylinder actuators need to be synchronized. The need for the design of a reconfigurable bending press tool (RBPT) control system prompted the research in the development of an automatic and synchronized system, suitable for press tool operations. The system had to de designed to be versatile in raising and thrusting of multi-cylinders with odd numbers. This paper describes the concept of the design of the control system that will allow the controlling of pressure, flow and synchronous cylinder movements, accompanied by position readings measured by position sensors. The system will work simultaneously; with a maximum assembled of units working together, typically in a number that fits the operation's needs. The aim of the proposed controller is to develop a position control system that incorporates features of a modular controller interfacing with position sensors and detecting the position of the hydraulic cylinder rod through commercially-of-The-shelf (COTS) components. © 2014 Published by Elsevier B.V.
