چکیده
B Abstract. Recently, in a paper of Chylla and Haase 2], a model of a multi-product semibatch polymerization reactor has been developed which is representative of those found in the speciality chemical processing industry. One of the aims in these processes is to keep a certain reaction temperature setpoint, in order to t the quality requirements for the polymer. In the present paper, the optimal solutions of the underlying optimal control problems of the Chylla-Haase reactor, which have been computed by a new direct multiple shooting method, are discussed. It can be shown that the rst of the two products for which physical data are given in 2] can be controlled along its required constant reaction temperature setpoint while, for the second product, this cannot be achieved because of certain mathematical and technical reasons.
