Open/closed loop bifurcation analysis for identification and model based control of fluidized catalytic crackers

摘要

Bifurcation analysis of a fluidized catalytic cracking unit was employed for proper model identification and synthesis of model based controllers. It is suggested that the investigation of bifurcation diagrams (open/closed loop analysis), using total circulation-catalyst flow rate and riser temperature set-point as the bifurcation parameters, should be included as a synthesis criteria for nonlinear identification and model based control purposes.
