Control no lineal por modos deslizantes de una columna de destilación binaria by Acosta Solano, Rubén Omar

“…Se realizaron pruebas en lazo abierto ante diferentes cambios tipo escalón para conocer el comportamiento dinámico y de estado estacionario. Se implementó un controlador Proporcional-Integral (PI), un control basado en la técnica de linealización por retroalimentación (FLC) y el control continuo por modos deslizantes (CSMC), se encontró que este ´ultimo presenta una convergencia más rápida hacia el set-point y un menor sobre tiro.…”
