1. A control method for controlling an electric-power-supply device for supplying electric power to a multi-phase electrical system, said device comprising at least one separate electric-power-supply assembly per phase of said electrical system, each electric-power-supply assembly comprising at least one battery pack defined by a state parameter and equipped with at least one battery intended to deliver a control voltage to the phase of the electrical system to which each electric-power-supply assembly is connected, while taking into account at least one setpoint value, the method comprising:
executing at least one correction block that receives, as input, each setpoint value and the state parameter of each battery pack of the electric-power-supply assemblies of the system; and
for each electric-power-supply assembly, determining, by said correction block, a correction value to be applied directly or indirectly to the setpoint value of the electric-power-supply assembly, while taking into account the difference between the value of the state parameter of the battery pack and the value of an optimal state parameter determined from the values of the state parameters of the battery packs of all the electric-power-supply assemblies.
