  • Deep convolutional neural network for mill feed size characterization 
    Olivier, Laurentz Eugene; Maritz, M.G. (Michael); Craig, Ian Keith (International Federation of Automatic Control, 2019)
    Knowing the characteristics of the feed ore size is an important consideration for operations and control of a run-of-mine ore milling circuit. Large feed ore variations are important to detect as they require intervention, ...
  • Dual particle filters for state and parameter estimation with application to a run-of-mine ore mill 
    Olivier, Laurentz Eugene; Huang, B.; Craig, Ian Keith (Elsevier, 2012-04)
    Measurements are not readily available for grinding mills owing to the nature of the milling operation. State and parameter estimation for a grinding mill which forms part of a run-of-mine ore milling circuit has been ...
  • Feed size distribution feedforward control for a grinding mill circuit 
    Maritz, M.G. (Michael); Le Roux, Johan Derik; Craig, Ian Keith (International Federation of Automatic Control, 2019)
    This paper proposes a method to measure and reject disturbances caused by changes in the ore distribution of the feed to a grinding mill circuit. A computer vision system is presented to measure the fraction of rocks in ...
  • Fractional order and BICO disturbance observers for a run-of-mine ore milling circuit 
    Olivier, Laurentz Eugene; Craig, Ian Keith; Chen, Y.Q. (Elsevier, 2012)
    Grinding mill circuits are hard to control due to poor plant models, large external disturbances, uncertainties from internal couplings, and process variables that are difficult to measure. This paper proposes a novel ...
