• Populations balance modelling of fluidised bed spray granulation
• Unstable steady-state operation with internal and external product classification
• Design of robust linear PI feedback controller
• Design on non-linear constrained model predictive controller
• Stabilisation of unstable process states
In this contribution different control approaches, ranging from standard linear control to non-linear model predictive control, are applied to fluidised bed spray granulation processes with internal and external product classification. These processes exhibit sustained non-linear oscillations in the particle property distribution, i.e. size distribution, that have negative influence on steady-state operation, for example a constant product mass flow with constant properties. The controllers are applied to stabilise these open-loop unstable steady-states.
Different control approaches are applied to fluidised bed spray granulation processes with internal and external product classification. These processes exhibit sustained non-linear oscillations in the particle property distribution that have negative influence on desired operation and product quality. The controllers are applied to stabilise these open-loop unstable steady-states.Figure optionsDownload as PowerPoint slide
