    Robust Nonlinear Model Predictive Control of a Run-of-Mine

    Abstract This brief investigates the feasibility of applying a robust nonlinear model predictive controller to a run-of-mine ore milling circuit and the conditions under which such a controller might be worthwhile implementing. The run-of-mine ore milling circuit model used consists of nonlinear modules for the individual components of the milling circuit allowing for arbitrary milling
