Improved Rod Plant Level Control with UNAC

For relatively little capital outlay, the metal delivery control system in the BHP Copper Rod Plant at San Manuel was significantly upgraded using the UNAC process simulation and control system. An accurate simulation of the metal delivery process was developed with UNAC, which was then used to design a robust controller capable of dealing with plant complexities such as noise, time delays, and nonlinearities. This controller was implemented online using UNAC. Thanks to the extensive preparatory simulation, the controller worked immediately and required no additional online "tuning". Operator response has been favorable, and the UNAC control system has become part of the standard operation of the plant.
