Abstract:
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 implemented. These estimates may then be used in an advanced control algorithm. The estimation
was done with dual particle filters as well as with a simultaneous estimation scheme, on simulated
data, to compare the performances. The sensitivity analyses for the different schemes show the class of
systems in which dual estimation may produce superior results.
