"A Soft Sensor for Biomass in a Batch Process with Delayed Measurements". XVII Latin American Conference of Automatic Control, IFAC, Medellín, Colombia, 2016, pp. 334--339.http://hdl.handle.net/11117/4258This paper presents a soft sensor to estimate the biomass concentration in a batch bioprocess used in production of δ-endotoxins of Bacillus thuringiensis, subject to delayed measurements. The soft sensor proposed is based on a cascade observer-predictor algorithm. The observer stage is based on a class of second order sliding mode algorithms, allowing a fixed time estimation of the biomass. Additionally, the prediction stage offsets the effect of the delay in measurements. Simulations show the feasibility of the proposed observer.engState observerChemical processDelayed measurementsinfo:eu-repo/semantics/conferencePaper
