AN EXPERT CONTROL SYSTEM FOR PURIFICATION PROCESS
(Department of Automatic Control Engineering,Central South University of Technology, Changsha 410083)
Abstract: For the purification subprocess of the hydrometallurgical process of zinc, an expert control system(ECS) has been designed and applied in a nonferrous metals smeltery. It consists of an expert control computer system and an I/A series distributed control system. Based on not only knowledge model but also mathematical model, the system completed expert optimization control for the purification process. The theory and techniques in the system design involve the control requirements, hierarchical model, design framework, expert optimization control and system implementation.
