State observer design for biomass and ethanol estimation in bioreactors using cybernetic models
Over recent years, the problem of multi-substrate microbial-growth modeling has received more and more attention. However, there is no evidence in the literature referring to state observer design that is applied to microbial growth described by cybernetic models. This paper focuses on the design of an asymptotic observer applicable to the estimation of biomass and ethanol in a two-substrate anoxic-fermentation process described by cybernetic modeling. Simulation results for the proposed observer show good performance for continuous, fed-batch and batch regimes.
