Modeling and simulation of the start-up operation of an IPGT by using NARX models

Accurate modeling requires the knowledge of bleed flows and inlet guide vanes control. However, the operational modes with modern dry low nitrogen oxide (DLN) and dry low emission (DLE) systems also involving fuel splits and bleed action are very complex. Since such pieces of information are usually unknown, or they are confidential manufacturer’s data, the adoption of a black-box approach allows the implicit incorporation of all these phenomena in a simple simulation model. For this reason, NARX models of start-up procedure for a heavy-duty IPGT are constructed in this chapter. The modeling and simulation are carried out on the basis of the experimental time-series data sets.
