Abstract

A method for controlling a gap minimization for an adjustable gap between a rotor and a housing of a gas turbine carried out on the basis of a correlation extracted from simulation data. If the actual value (PI) lies below the lower threshold (PU), the gap minimization is deactivated, whereas if the actual value lies above the upper threshold (PO), the gap minimization is activated. The gap minimization is activated between the thresholds (PU, PO) if the actual value lies above the threshold (PG) but is deactivated if the actual value (PI) lies below the threshold (PG).
