This work presents a dynamic lumped parameter model for microalgal production in tubular photo-bioreactors. The model is made up of fluid dynamic processes, mass transfers and biological phenomena, all of them being based on chemical, physical, and biological principles. The aim of this work is to develop a simplified model including the main non-linear dynamics of the process, so that a trade-off between complexity and performance can be found. The model can be used for advanced control purposes, as a tool for the design and operation optimization of photobioreactors, or even as a supervision system of unmeasured variables. The characteristic parameters of the model were calibrated and validated under different conditions of solar radiation, using experimental data from a pilot facility consisting in an outdoor tubular photobioreactor. Furthermore, the proposed model is compared to other existing models (linear, distributed parameters and NARMAX) through a set of detailed simulations.
