Supervisory Control Project of a Copper Solvent Extraction Pilot Plant

The experience developing a supervisory control and information systems in a SX pilot plant is presented. The plant is located at the Process Control Laboratory, Santa María University, in Chile. The control system is organized at three levels, local, hydrodynamic and metallurgic supervisory controls, in an architecture including field controllers, PLC and PC networks. The main objectives are to develop and test intelligent techniques in a hybrid system, and to study measurement and supervisory control problems. It is expected to produce reliable results that will contribute to improve the efficiency of this emerging and important process.
