METHOD FOR CONTROLLING A ROTORCRAFT, ASSOCIATED ROTORCRAFT AND COMPUTER PROGRAM

The present invention relates to a method for controlling a rotorcraft (1), said rotorcraft (1) comprising at least two combustion engines (2, 3), at least one control system (13) and a transmission system (4), said at least two engines (2, 3) being mechanically connected to said transmission system (4) respectively by at least two couplings (25, 26). Such a control method comprises at least an identification of an engine regulated in N2 (2), an identification of an engine not regulated in N2' (3) and a generation of a control setpoint limit of at least a first control system (12) of the engine regulated in N2 (2) and dependent on the rotation speed N2 of at least a first output shaft (5) of the engine regulated in N2 (2).
