Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2006. / The distributed control system network involves analog data acquisition nodes interconnected through CAN and USB protocol interfaces to form a network. The network is designed to be generically applicable to various control problems. This network of controllers was specifically utilised on a scaled-down electrostatic roll separator plant used in the mineral processing industry. A SISO and a MIMO regulator was designed to demonstrate the regulation of plant parameters. The MIMO regulator was employed in a scheme that optimises the plant yield automatically. Analog data acquisition nodes were designed and built especially for the purposes of this project. These nodes were installed on the electrostatic roll separator plant. PC based application software was written so that plant ID experiments could be performed. SISO and MIMO regulators along with a yield optimising scheme was designed and implemented in the application software. Both SISO and MIMO regulators successfully regulated plant outputs. The nonconducting mineral product grade was regulated by the SISO regulator. The non-conducting mineral product grade and conductor mineral mass flow was regulated by the MIMO regulator. The yield optimiser successfully employed the MIMO regulator to optimise the plant yield automatically.
