Dual particle filters for state and parameter estimation with application to a run-of-mine ore mill

摘要

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 circuithas been implemented. These estimates may then be used in an advanced control algorithm. The estimationwas done with dual particle filters as well as with a simultaneous estimation scheme, on simulateddata, to compare the performances. The sensitivity analyses for the different schemes show the class ofsystems in which dual estimation may produce superior results.
