Abstract

Optimal operation of fed-baich bioreactors is ail important practical issue. Since control actions are saturation-limited, the optimal control consists usually of both singular and bang-bang arcs. However, its realization requires good model knowledge and also measurement of all state variables, requirements hardly satisfied in real applications. In this paper a method is proposed, for a class of bioreactors, to robustly optimize the operation when few measurements are available and die model is uncertain. Such control law is justified and its properties analyzed. The class of processes addressed includes a biomass growth bioreactor and an experimental wastewater treatment plant for degrading toxicants.
