Frequency Domain Model Simplification of Cumulative Mass Fraction in CMSMPR Crystallizer

frequency domain model simplification of cumulative mass fraction in cmsmpr crystallizer

in this contribution, linearized dynamic model of cumulative mass fraction (cmf) of potassium nitrate-water seeded continues mixed suspension mixed product removal (cmsmpr) crystallizer is approximated by a simplified model in frequency domain. frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. however, the cmf fr...

Heuristic Process Model Simplification in Frequency Response Domain

Frequency response diagrams of a system include detailed and recognizable information about the structural and parameter effects of the transfer function model of the system. The information are qualitatively and quantitatively obtainable from simultaneous consideration of amplitude ratio and phase information. In this paper, some rules and relationships are presented for making use of frequenc...

Effect of Different Nucleation and Growth Kinetic Terms on Modeling Results of KNO3 CMSMPR Crystallizer

The aim of this contribution is a survey of different nucleation and growth kinetics terms effects on modeling results of KNO3 Continuous Mixed Suspension Mixed Product Removal (CMSMPR) crystallizer. By studying the four different states in modeling, results show that, although these terms for similar crystallization system and operating conditions are similar, there is very different dynamic b...

Frequency Domain Model (In)Validation

ABSTRACT Classical validation methods accept or reject a model as a valid representation of a plant. However this quantization has several problems: i) Models are neither good nor bad but have a certain valid frequency range. ii) This gives no guess on the failure reasons or the way the model could be improved. iii) In iterative identification and control approaches undermodeling is usually pre...
