This paper discusses a two-level strategy integrating dynamic trajectory optimization and control for the operation of chemical processes. The benefit of an online dynamic re-optimization of operational trajectories in case of disturbances is illustrated by a case study on a semi-batch reactive distillation process producing methyl acetate.
— This work discusses reference trajectory relevant model based feedforward design. For motion systems which contain at least one rigid body mode and which are subject to reference trajectories with mostly low frequency energy, the proposed feedforward controller improves tracking performance significantly. The feedforward controller may be of much lower… (More)
In this report a literature survey on the possibilities of fuzzy control for mechatronic systems is described. The motivation for this inquiry is the limitation of linear control, emerging among others in the case of plant nonlinearity and conflicting requirements on performance. Fuzzy control is considered here as a control technique which possibly enables… (More)
