Power sharing in an aircraft using distributed control

An installation for exchanging power in an aircraft, comprising:

• a voltage bus configured to present a bus voltage (VDC);
• a low-pressure (BP) electromechanical converter configured to exchange power (PBP) between the voltage bus and a low-pressure body of a turbomachine of the aircraft;
• a high-pressure (HP) electromechanical converter configured to exchange power (PHP) between the voltage bus and a high-pressure body of the turbomachine of the aircraft;
• for each of the low-pressure and high-pressure electromechanical converters, a voltage control module configured to control the bus voltage (VDC) by controlling the corresponding electromechanical converter so as to adjust the power exchanged (PHP, PBP) by the electromechanical converter in question;
• a computer configured to provide a sharing setpoint (S) between the exchanged powers (PHP, PBP), the sharing setpoint (S) varying over time;
• and
• for at least one of the electromechanical converters
• a communication module configured to receive the sharing setpoint (S) supplied by the computer and an evaluation (PBP°, PHP°) of the power exchanged (PBP, PHP) by the other of the electromechanical converters, and
• a module configured to comply with the sharing setpoint (S) to adjust the power (PHP, PBP) that is exchanged by the electromechanical converter in question so as to comply with the received sharing setpoint (S), taking into account the received evaluation (PBP°, PHP°) of the power exchanged (PBP, PHP) by the other of the electromechanical converters.
