Integrated control and sensing platform for biopharmaceutical cultivation process high-throughput development and production

Deliverables

Transferrable and generic chemometric model procedures are ready for application (models obtained by MBR can be used in STR)

The results of the transferability of models developed using MBR to apply in STR are obtained. The conditions and procedures how to transfer are determined. Under which conditions and how models obtained by MBR can be used in STR.

Off-line glycosylation/titre assays after sample purification/preparation on fluidic platform

Different glycan assay formats will be tested for integration into microfluidic platform.

Mechanistic models with different complexity levels related to their use (description/soft sensor/control)

Mechanistic models will be derived from the experimental data and obtained through ordinary differential equation systems to describe the component concentration evolutions with respect to a kinetics and b transfersdilutions The general model complexity related to the number of considered pseudobioreactions will be based on the physical knowledge while the parameters will be identified by a dedicated identification procedure validated with the datasets

Multivariable predictive robust controllers of the metabolites

In accordance with available online measurements from hardware and software sensors a robust minimax nonlinear model predictive control strategy Robust NMPC will be developed to control the main metabolites ie to respect a priori optimal metabolite levels Process optimality will be described by the nonlinear constrained problem solved by the NMPController

Spectrophotometric method decision-diagram for specification of best method

Spectrophotometric method decisiondiagram for specification of best method Raman NIR MIR 2D fluorescence or wavelength combinations for specific applications

Data-driven models with different complexity levels related to their use (description/soft sensor/control)

Data-driven models will be derived by applying MLPCA to the datasets to determine the data-driven required number of pseudo-bioreactions. In a second step, a decision on the kinetic structure (grey-box vs black-box) will be taken with respect to the data content. Eventually, an adapted identification procedure will be applied and validated with the datasets.

Software sensors using the previously obtained models

A general observability mapping will be determined based on the previously obtained models from D8.1 and D8.2. Necessary on-line measurements will be selected and software sensors will be derived from the models and these measurements. First off-line validations of the resulting software sensors will be achieved and used as basis for further on-line validations using closed-loop controllers.

Chemometric models methodology is fixed and can be utilized by partners

The best modeling methodology is determined (such as PCR, PLS or neural network, support vector regression) and can be applied by the partners

Spectral pre-processing procedures (such as outlier detection, noise reduction and smoothing) are implemented

The algorithms of outlier detection, noise reduction and smoothing are implemented and validated. Furthermore preprocessing procedures like deviation-, distance- and density-based approaches are implemented in the evaluation program.
