As far as the feeding mode was concerned, constant-speed feed was more effective than batch-wise feed. The abnormal cellular form was often observed when glucose was batch-wise fed.
Thus, the perturbation model is updated in a batch-wise manner. After completion of each batch, a batch-wise perturbation model is identified linearized around the control trajectory for that batch.
