“…13,14 The closed-loop stability of EMPC methods are also discussed in the literature. [12][13][14][15][16] Although lots of literature considered the application of classic MPC in the field of hydrometallurgy, [17][18][19] few papers apply the EMPC approach to this field. In order to improve the dynamic operation of GCLP, EMPC should be adopted to achieve both transient and steady-state economic optimization simultaneously.…”

“…El proceso hidrometalurgia del cobre, compuesto por las etapas de Lixiviación (LIX), Extracción por Solvente (SX) y Electro-obtención (EW) es uno de los más importantes métodos de producción de cobre desde minerales oxidados de baja ley (Komulainen, Doyle III, Rantala, & Jämsä-Jounela, 2009). La investigación en este proceso, ha sido enfocada principalmente en los procesos químicos y equipos asociados.…”

“…La investigación en este proceso, ha sido enfocada principalmente en los procesos químicos y equipos asociados. Hasta el presente, el control de los procesos de SX-EW ha recaído sobre simples lazos de control y sintonía manual, con operadores manipulando activamente los set-point (SP) para controladores de nivel básico o de primer nivel (Komulainen et al, 2009;Bergha, Jämsä-Jounela, & Hodouinc, 2001). Un factor clave que reduce la eficiencia de plantas de SX es la metodología reactiva que los operadores de estas plantas están obligados a realizar, basados en análisis de laboratorio de los flujos fuera de línea, los cuales ya han sido procesados a través de la planta (Li, Yuan, Yang, & Huang, 2007).…”

“…Feedforward control is one of the additional functionalities that can be added to conventional PI and PID control to achieve enhanced performance (Piccagli and Visioli, 2009), with the use of feedforward control reported for various industrial processes (Sanchis and Peñarrocha, 2009;Komulainen et al, 2009;Graichen et al, 2006). Reported use of this method in the smelting industry has, however, been very limited due to unavailability of suitable process models.…”
