Modeling and control of the melt index in HDPE process

摘要: We investigate the model for an industrial isothermal HDPE slurry reactor. The model, consisting of several nonlinear equations, can be linearized to give sets linear time invariant state space model. effectiveness is verified by numerical simulations. A simple predictive control scheme constructed based on value melt index obtained from values manipulated and controlled variables generated scheme. performance evaluated comparison between computed measured values. shows good tracking in believe that developed present study effectively used predict process as well index.
