[PDF] Appliion of Soft Constrained MPC to a Cement Mill ...

Abstract In this paper we develop a Model Predictive Controller (MPC) for regulation of a cement mill circuit. The MPC uses soft constraints (soft MPC) to robustly address the large uncertainties present in models that can be identified for cement mill circuits. The uncertainties in the linear predictive model of the cement mill circuit stems from large variations and heterogeneities in the ...

SLAB ON GRADE REINFORCING DESIGN

an unreinforced concrete slab. With some limitations, reinforcement for slabs can be sized using the Subgrade Drag Theory in order to increase the spacing of control or construction joints. The result is a lightly reinforced slab designed to offset the effects of temperature and shrinkage of the concrete.
