Self tuning control of fermentation process

TL;DRAbstract

Control of fermentation processes is a complex problem due to the inherent non-lineanties and time varying characterstics of the process. The application of conventional single loop analogue controllers provides poor control due to problems in tuning individual loops and the lack of ability to implement complex controllers. The application of standard optimal techniques is compounded both by the complexity of the process and the lack of adequate models as a result of poorly understood dynamics. The lack of important transducers for product measurement coupled with the time varying parameters in a fermentation process provides a natural test for adaptive control techniques.
