Abstract
In order to limit the flame temperature peaks following sudden load variations, corresponding control is planned of the position of the blades () of the distributor with variable geometry, of a single-shaft gas turbine (); in particular, the control system proposed comprises a direct-action regulator () consisting of a calculation unit (), which implements the simplified running model of the gas turbine (), and a feedback regulator (), which makes it possible to recuperate any inaccuracies of the direct-action regulator (), caused by variations of the performance of the turbine (), relative to those planned by the model, or caused by modelling errors.
