The chemical reactor or bioreactor is physically at a central position in a process, and often with a decisive role on the overall technical and economical performance. Even though application of feedback control on reactors is gaining momentum and on-line optimization has been implemented in industry, many reactor control problems are still left unsolved or only partly solved using open loop strategies where disturbance rejection and model inaccuracies have to be handled through manual reactor control and feedback control of raw material preprocessing and product purification operations.

For bioreactors the theory and practice of reactor design, dynamics and control have to be adapted to the peculiarities of the biological catalysts. Enzymes, the protein catalysts, are the simplest ones, which have many common features with chemical catalysts. The living cells are much more complex, these growing and adaptive catalysts present several challenging control problems.

This survey deals with recent progress in model based control of reactors and with underlying modelling, identification and dynamical aspects. Of the large variety of reactors the survey touches upon progress in control of a few types, with the main focus on the industrially important fixed bed reactor, batch, fed batch and continuous bioreactors.
