On-line estimation of the reaction rates in bioreactors from multirate sampled outputs with multiple delays

This paper provides a simple high gain continuous-discrete time observer to handle the estimation problem of the reaction rates in bioreactors using delayed sampled measurements of the component concentrations in the context of multirate sampling of the outputs each one of which is affected by a constant delay The rational behind the proposed observer design consists in the consideration of an appropriate corrective term provided by a linear...
