Optimal model-based experimental design in batch ...

Jan 04, 2000  The model-based experimental design of batch crystallizers is investigated. A dynamic programming formulation minimizes the volume of a confidence hyperellipsoid for the estimated nucleation and growth parameters over the supersaturation profile and the seed characteristics, namely, the crystal mass, mean size, and width of the seed distribution.

Efficient online model-based design of experiments via ...

Feb 02, 2019  The typical procedure for identifying a batch system starts from finding the optimal experimental design regarding a single batch, collecting the measurement data up to a termination instant, and then finding a parameter estimate through regression analysis. The process is repeated until the precision of parameter estimate is satisfactory.

Nov 15, 2009  The fed-batch process operation gives always a significant higher precision of the parameters compared to the batch mode. If the rough estimated parameter values, with which the optimal experimental design is carried out, are just known with low accuracy equidistant measurement points are in favour to model-based optimal experimental design.
