Abstract

In this paper, an observer-based control system is presented for the regulation of biomass concentration in bioreactors. The importance of the observer is highlighted by the dependency of the feedback linearising controller on the measurements of biomass concentration. Further, the discrete nature of output substrate concentration is considered and the performance of the system proposed is analysed through a simulation study using Matlab/Simulink. This study is also used to determine the limit on the sampling partition diameter for which the observer and controller designed give satisfactory performance. The implemented observer-based control system showed satisfactory performance both in terms of stability and convergence for given values of sampling partition diameters.
