Batch and semi-batch polymerization reactors with specified trajectories for certain process variables present challenging control problems. This work reports, results and procedures related to the application of PI ...

Epilepsy is frequent all over the world, occurring independent of gender, age, race or social status. The highest prevalence rates occur in countries under development and are due to infectious parasitic diseases, like ...

The correlation analysis (CRA) theory is an important tool in the system identification field. Among its utilities, the correlation analysis enables the mathematical modeling of a process, through the estimate of its impulse ...

This study presents closed-loop results regarding the production of high-density polyethylene with Ziegler–Natta and Phillips catalysis. The multivariable control algorithm based on the generalized predictive control ...

This paper presents a fuzzy model-based predictive hybrid controller (FMPHC) for polymerization processes based on Takagi−Sugeno models and moving horizon methodology. Such processes are characterized by strongly nonlinear ...

The technique of experimental design is used on an ethylene polymerization process model in order to map the feasible optimal region as preliminary information for process optimization. Through the use of this statistical ...
