Identification and control of continuous fermentation processes are dif‐ficult tasks due to the complexity and high coupling of dynamic behaviour of this kind of system. In this work is implemented an on‐line estimation technique of the main uncertainties of a fermentation processes (e.g. specific growth rate, biomass concentration and yield coefficient) based on a mass balance, to generate a linearising feedback control law that provides a robust stabilisation against uncertainties. By numerical simulations the performance of the closed‐loop system and the controller design procedure is illustrated.
