Integrated robust optimal design and control of an MSMPR crystallization process
AIChE Annual Meeting 2003, San Francisco, USA
A recent approach , , , that guarantees a user-specified dynamic behavior of the design is adopted to the integrated design and control of an MSMPR crystallization process. In the approach an optimization problem is formulated which includes constraints that separate the regions of desirable process behavior from regions of undesirable process behavior. These constraints are rigorously derived on the basis of nonlinear dynamics theory. By means of a case study not only an economically optimum operating point, but also a controller tuning that guaranties a specified performance of the closed-loop crystallization process is found in the face of parametric uncertainties. The results demonstrate that the formulation of an integrated optimal design and control problem with the adopted approach is promising for the underlying process model.
