Abstract

Inspired by a recent review article on the Automation of the Mining, Mineral, and Metal Processing Industry (MMM), this paper will discuss some important ”patches” of computer aided measurement processes in the MMM processing industries. Both evaluation of measurement data, as well as real-time control of the measurement processes will be covered. Notes will be given on the use of machine vision, electrochemical potential, optical emission spectrometry, and X-ray spectrometry. Some visions for the future will be offered.

Abstract

Grinding systems are often modelled by multivariable impulse response or weighting function matrices. These kind of models are very suitable for design of model predictive controllers. Two predictive control algorithms have been developed and tested with two simulated models of grinding systems. Their design is based on decoupling of the steady state interactions. The dynamic interactions cannot be eliminated but their strengths are reduced by dynamic compensation.
