This paper applies a neural-network-based approximate dynamic programming (ADP) method, namely, heuristic dynamic programming (HDP), to an industrial sucrose crystallization optimal control problem. The industrial sucrose crystallization is a nonlinear and slow time-varying process. It is quite difficult to establish a precise mechanism model of the crystallization, because of complex internal mechanism...
The sugar factory's sugar crystallization is the last and the most crucial step. It incorporates both the heat and mass transfer. Controlling the supersaturation stability is the key factor that impacts the boiling sugar in the crystallization process. As a result, we must keep supersaturation in metastable zone (keeping the supersaturation in 1.20-1.25) in order to speed up the crystallization rate...
