Resumo: | Modeling and simulation applied to level control of oil and gas separators in production facilities is a very important tool because makes possible to perform tests that probably could not be viable due to operation and safety constraints. Asides the level dynamics can be well understood regarding the physical model, there will always be non-linearities to approach using a system identification procedure, requiring reasonable care on linear model identification. In order to assure a desired control performance, an adaptive control strategy has been proposed for level control for an oil and gas separator using the gain scheduling technique. Based on a first order process without time delay, the static gain and time period were determined for each point inside the operational space range of the equipment and by Internal Model Control (IMC), the tuning matrix found and converted into a function of operational parameters using polynomial interpolation methodology for future application in a real commercial PI controller. The horizontal separator was simulated using MATLAB/SIMULINK® and data from a real separator vessel were used to identify and validate the proposed process modeling in attempt to test an adaptive control strategy for practical applications. Once the GSC was implemented, simulations were performed over the non-linear system and results have shown better performance indexes for GSC while compared to the conventional PI controller for both servo and regulatory problems with reductions up to 17.65% for IAE, 29.88% for ISE, 16.38% for ITAE, 29.00% for ITSE and 13.20% for Control Effort (CE). |

Aunque la dinámica del nivel es bien conocida desde el punto de vista físico, siempre habrá no linealidades inherentes que deberán ser verificadas mediante la realización de procedimiento de identificación de modelo, necesitando razonable precaución en la aplicación de herramientas de modelo lineal. Con el fin de garantizar el rendimiento deseado, se propuso una estrategia de control adaptativo para realizar el control de nivel de un separador de petróleo y gas natural utilizando la técnica Gain Scheduling Control (GSC). Tomando como base el modelo de un proceso de primer orden (First Order Process - FOP) sin tiempo muerto, las ganancias estáticas y constantes de tiempo fueron determinadas para cada punto perteneciente al rango (range) operacional del equipo y, por el método de sintonía IMC, encontrada la matriz de sintonía para un controlador de tipo PI, implementado en un controlador PI comercial utilizando la metodología de interpolación polinómica. El separador horizontal bifásico se ha simulado utilizando si el paquete computacional MATLAB/SIMULINK® y datos de proceso de un vaso separador en planta real fue utilizado para identificar y validar el modelado propuesto en un esfuerzo de probar la estrategia de control adaptativo para aplicaciones prácticas. Por simulación del modelo no lineal, fue posible confirmar, a través de índices de calidad, mejor desempeño del controlador GSC comparado a un controlador PI convencional tanto para el problema servo como para el problema regulatorio con reducción de hasta 17,65% en el índice IAE, 29,88% en el índice ISE, 16,38% en el índice ITAE, 29,00% en el índice ITSE y 13,20 % en esfuerzo de control (CE).Os conceitos de modelagem e simulação aplicados ao controle de nível em processamento primário de petróleo e gás constituem uma ferramenta de grande importância por permitirem a realização de testes que provavelmente não poderiam ser viáveis devido a restrições operacionais e de segurança.
