Project objectives
CAFÉ Project IPA, Paris October 19, 2010
To provide new paradigms for the smart control of food processes, on the basis of four typical processes in the areas of bioconversion, separation, preservation and structuring.
Novelty : to combine PAT/sensing devices with models : 1) to extract as much as possible information from the process/plant (unmeasured variables defining product quality) 2) to transfer it in a reliable/usable way in physical models; 3) to develop control methods to keep uniform quality and production despite the variability in the raw material and/or to respond to sudden changes in the demand.

WP6: Process design and optimization
CAFÉ Project IPA, Paris October 19, 2010
Objectives • To have efficient and robust dynamic optimisation methods for parameter estimation, model calibration and optimal operation design. • To compute optimal operation policies for the different processes: off-line applications and Real-Time Optimization (RTO).
• To develop an optimal experimental design approach

WP7: Monitoring and Control
CAFÉ Project Mid-Term Review August 30, 2010
Objectives
• To design control strategies (optimal control, extremum seeking) that rely on the available on-line information provided by the sensors and which are able to comply with optimal trajectories generated within WP6. These control laws will be based on process models and will account for the uncertainties (model, external disturbances). • To design and evaluate new control strategies based on the optimal control laws and the available hardware/software sensors • To evaluate the long-term behaviour of the plant and the improvement obtained in the process by the control strategies

The scientific management of CAFE is a challenge
CAFÉ Project Grant agreement n°KBBE-212754
Mid-Term Review August 30, 2010
• Large collaborative project (16 partners) • Diversity of skills and backgrounds, plus a balance between academia and industry • Diversity of control problems (illustrated by the 4 case studies) • A priori 4 project unifying threads (the case studies) In the end : the notion of paradigms has to have a structuring effect/impact
13
• Importance of WP8 (integration) 1) coordination/integration of the scientific/technological knowledge towards paradigms
2) integration of the results into a unified control system • Incentives to look for paradigms within : - each WP - each case study • Building of paradigms : long-term process
The notion of paradigms is central
