Control method and control device for a hybrid turbine engine

A control device for a hybrid turbine engine, the control device comprising:

• an input configured to receive a sequence of measurements of the engine speed of the hybrid turbine engine;
• a memory configured to record the sequence of measurements and a sequence of speed setpoints;
• a computer configured to determine a sequence of deviations, each deviation being a difference between one measurement of a sequence of measurements of the engine speed of the hybrid turbine engine, and one setpoint of a sequence of engine speed setpoints, the computer being configured to determine a variation of fuel flow rate and a variation of electrical torque, the computer being configured, in order to determine the variation of fuel flow rate and to determine the variation of electrical torque, to use a difference between a last measurement of the sequence of measurements and a penultimate measurement of the sequence of measurements, a last deviation of the sequence of deviations, the last deviation being temporally associated with the last measurement, and a sum of the deviations of the sequence of deviations;
• and
• an output configured to provide a command to the hybrid turbine engine.
