A feasibility study for an IMC application in the mining industry

This project is a feasibility study using Internal Model Control strategies to optimise the performance of a secondary and tertiary crusher stage at a mine. First, a mathematical model of the plant is_ extracted and simulated. The viability of using IMC on an unstable process is considered. Various general objectives are then explained, whereafter the manually controlled plant is evaluated. Three strategies are proposed that control the bin levels to optimise buffer capacity so that crusher throughput is increased and efficiency improved. These are tested on a simulator fed with real plant data to reveal their properties. Finally, an implementation scheme is then proposed.
