Hybrid fuzzy-GMC control of gas-phase propylene copolymerization in fluidized bed reactors

A modified two-phase model is presented to describe the process of gas phase propylene and ethylene copolymerization in a fluidized bed reactor (FBR). Entrainment of solid particles in the FBR is considered in the model, as an improvement to the original two-phase model. Non-linearity of this proces...
