TLDR
In this paper, interval state estimation methods are proposed in the situation, quite common in biological systems, where measurements are only available at discrete, and possibly rare, times, and the attention is focused on defining predictors preserving the boundedness of the state variables between two measurement times assuming bounded uncertainties.About:

Hurdles and challenges for modelling and control of microalgae for CO2 mitigation and biofuel production
Olivier Bernard,Olivier Bernard +1 more
TL;DR: The Droop model, which has been widely used to predict microalgal behaviour under nutrient limitation, is reviewed, and a model for raceways or planar photobioreactors, when both light and nutrients are limiting is details.

Review and classification of recent observers applied in chemical process systems
TL;DR: This paper reviews the applications of recent observers to chemical process systems and classify them into six classes, which differentiate them with respect to their features and assists in the design of observers.

Interval observers for discrete-time systems
TL;DR: In this article, it was shown that for any time-invariant exponentially stable discrete-time linear system with additive disturbances, time-varying exponentially stable interval observers can be constructed.

Robust interval observers and stabilization design for discrete-time systems with input and output
TL;DR: This interval observer applies in the presence of unknown bounded nonlinear terms and additive disturbances and is used to achieve asymptotic stability through an appropriate choice of dynamic output feedback.

Interval observers for discrete-time systems
TL;DR: It is shown that, for any time-invariant exponentially stable discrete-time linear system with additive disturbances, time-varying exponentially stable continuous-time interval observers can be constructed.

Vitamin B12 and Marine Ecology. IV. The Kinetics of Uptake, Growth and Inhibition in Monochrysis Lutheri
TL;DR: Specific growth rate in the chemostats was found not to depend directly on medium substrate concentration but on the concentration within the cells (cell quota), obeying a hyperbolic equation of the form
Journal ArticleDOI
Interval observers for uncertain biological systems
TL;DR: In this paper, the authors present a technique for the dynamic estimation of bounds on unmeasured variables (or parameters) of an uncertain dynamical system, which relies on interval observers: from (possibly time varying) intervals on the uncertainty and measurements, they compute guaranteed intervals for the variables.

CO2 mitigation and renewable oil from photosynthetic microbes: a new appraisal.
TL;DR: In this paper, the authors report the results of a privately funded US$20 million program that has engineered, built, and successfully operated a commercial-scale (2 ha), modular, production system for photosynthetic microbes.
