Abstract

Wastewater treatment is a biological process which involves the streaming of solid waste products in tubes and makes use of sensors which provide outputs at distinct instants of time. These issues lead to problems in the control of the output, which is the substrate concentration. In this work, we present an observer and a controller which is used to control the biomass concentration of such bioreactors in the presence of delayed and discrete measurements. The aim of this paper is to make a realistic analysis of the proposed observer-based control system and conclude on the effects of delayed measurements on the maximum possible sampling partition diameter as well as to study the effect of the sampling rate on the maximum possible delay. The results obtained confirmed the satisfactory performance of the system.
