Abstract:
This paper deals with the design of an interval observer for estimation of some state variables in an uncertain biotechnological process. The observer is applied to estimate the biomass concentration in an anaerobic bioprocess with a simplified mathematical model. In this approach only the bounds of the biomass concentration and the synthesis product concentration can be estimated by using appropriately designed interval observer. Based on this observer a robust-adaptive control strategy of a substrate inside the reactor is proposed. The performance of the proposed adaptive control strategy is illustrated by numerical simulations applied in the case of an anaerobic bioprocess for which kinetic dynamics are highly nonlinear, time-varying and incompletely known.
