Observability analysis of nonlinear
tubular (bio)reactor models: a case
study
Latin Abstract :
This paper deals with the observability analysis of nonlinear tubular bioreactor models. Due to the lack of tools for the
observability analysis of nonlinear infinite-dimensional systems, the analysis is performed on a linearized version of the model
around some steady-state profile, in which coefficients can be functions of the spatial variable. The study starts from an example of
tubular bioreactor that will serve as a case study in the present paper. It is shown that such linear models with coefficients dependent
on the spatial variable are Sturm–Liouville systems and that the associated linear infinite-dimensional system dynamics are described
by a Riesz-spectral operator that generates a C0 (strongly continuous)-semigroup. The observability analysis based on infinitedimensional
system theory shows that any finite number of dominant modes of the system can be made observable by an
approximate point measurement.
