We focus on an important phase of the proportioning → burning → grinding operation triplet that essentially deter- mines the cement quality; namely, the composition control of the raw mill system. We begin by describing the applica- tion of the generic optimal.

Control of Hybrid Systems - Verimag

The above discrete-time hybrid models can be proven to be equivalent (under some mild assumptions). Equivalence implies that for all feasible initial states and for all feasible input trajectories, the models yield the same state and output trajectories. [Heemels, De Schutter, Bemporad, 2001].
