Control no lineal por modos deslizantes de una columna de destilación binaria
Publicado 2015“…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.…”
