Abstract. This paper describes a NOx control system in a combined cycle power plant. The aim is to increase the control performance of a NOx decomposition process by improving measurable disturbance compensation. Extended Generalized Predictive Control algorithm is used. The typical predictive model in GPC algorithms (ARIMAX) is extended by a measurable disturbance vector.
