  • An EKF observer to estimate semi-autogenous grinding mill

    The SAG mill model of Napier-Munn et al. was used to describe the grinding process, along with a novel ball charge model and a mill-liner model. Using measurements of the mill charge weight and size-by-size solids discharge, Apelt et al. 26 used 29 measurements to estimate 37 states and 7 parameters with an extended Kalman filter EKF .
