In order to limit the flame temperature peaks following sudden load variations, corresponding control is planned of the position of the blades ( 13 ) of the distributor with variable geometry, of a single-shaft gas turbine ( 18 ); in particular, the control system proposed comprises a direct-action regulator ( 21 ) consisting of a calculation unit ( 22 ), which implements the simplified running model of the gas turbine ( 18 ), and a feedback regulator ( 20 ), which makes it possible to recuperate any inaccuracies of the direct-action regulator ( 21 ), caused by variations of the performance of the turbine ( 18 ), relative to those planned by the model, or caused by modelling errors.
