1. Subspace predictive control. / Controle preditivo com enfoque em subespaços.
Model Predictive Control (MPC) technology is widely used in chemical process industries. Subspace identification (SID) on the other hand has proven to be an efficient alternative for classical system identification methods. Based on the results from MPC and SID, it was developed in the late 90s a new control approach, called Subspace Predictive Control (SPC)

2. Simulação, analise e otimização das colunas atmosferica e debutanizadora da unidade de destilação do refino de petroleo / Simulation, analysis and optimization of the atmospheric and debutanizer columns of the petroleum distillation unit
The crude distillation unit is the most important in the refining process. Its importance is due to the fact that this unit is responsible for the first fractionation of the petroleum in various products (fractions) as naphtha, kerosene, diesel and others. Some of these fractions obtained are removed as final product and others can be processed in other unit

3. Técnicas de inteligência artificial para a geração dinâmica de set points para uma coluna de destilação
No presente trabalho, aplicamos técnicas de inteligência artificial em um sistema simulado de destilação de petróleo, mais especificamente em uma coluna debutanizadora. Nesse processo, o produto que chega à coluna, conhecido como LGN, é fracionado por meio de aquecimento. Os componentes mais leves são transformados em vapor, que vão constituir o GLP

4. Including model uncertainty in the model predictive control with output feedback
This paper addresses the development of an efficient numerical output feedback robust model predictive controller for open-loop stable systems. Stability of the closed loop is guaranteed by using an infinite horizon predictive controller and a stable state observer. The performance and the computational burden of this approach are compared to a robust predic

5. Robust predictive control of a gasoline debutanizer column
This paper studies the application of Model Predictive Control to moderately nonlinear processes. The system used in this work is an industrial gasoline debutanizer column. The paper presents two new formulations of MPC: MMPC (Multi-Model Predictive Controller) and RSMPC (Robust Stable MPC). The approach is based on the concepts of Linear Matrix Inequalities
