Observers are computational algorithms designed to estimate unmeasured state variables
due to the lack of appropriate estimating devices or to replace high-priced sensors in a plant …

Environmental quality is becoming an increasing concern in our society. In that context,
waste and wastewater treatment, and more specifically biological wastewater treatment …

Understanding the growth characteristics of microorganisms is an essential step in
bioprocessing, not only because product formation may be growth-associated but also …

In this paper, we propose a global theoretical framework for the analysis of bioreactor
dynamics. We concentrate on the problem of kinetic rates' estimation inside the reactor. We …

Engineering systems experiencing high-rate dynamic events, including airbags, debris
detection, and active blast protection systems, could benefit from real-time observability for …

This paper deals with the tuning of observer-based estimators. Initially, these algorithms
were designed for estimating on-line kinetic parameters, like specific growth rates, in …

In this paper, we propose simple nonlinear observer-based estimators for the on-line
estimation of kinetic rates in fermentation processes. These estimators, designed in …

The increasing performance demands on controlled chemical operations, coupled with the
lack of appropriate measurement technology, motivates the need for nonlinear inferential …

The design of simple nonlinear observer‐based estimators for the on‐line estimation of the
reaction rates in chemical and biochemical processes is presented. The proposed …

Engineering systems experiencing events of amplitudes higher than 100 gn for a duration
under 100 ms, here termed high-rate dynamics, can undergo rapid damaging effects. If the …
