The paper deals with robust compensator control of continuous aerobic fermentation processes described by a set of non-linear differential equations. For design purposes the non-linear model is transformed into a linear one with interval parameters. the robust state-space compensator is designed according to the internal model principle. Biomass concentration is estimeted on-line by an observer. Substrate concentration is obtained by model-based or indirect measurement. The theoretical results are verified by simulations in different cases. Robustness and simple realisation are important features of the proposed algorithms.
