(Elsevier, 2024)
The surge tank in a bulk tailings treatment plant aims to reject flow and density
disturbances. However, for large disturbances, there may be an inversion in the gain between
the water inflow and tank slurry density for ...

(Elsevier, 2024)
The plant-model ratio, developed to diagnose model-plant mismatch present in
model-based controllers, inherits the same limitations from the frequency-based analysis that
the method is based on. Nonetheless, the plant-model ...
