1. A method for controlling a mechanism having a dissymmetric behavior, the method comprising the following steps:
when a setpoint signal indicates to operate the mechanism along a first direction, a control module applies a first corrector to the setpoint signal in order to generate a control signal; and
when the setpoint signal indicates to operate the mechanism along a second direction, the control module applies a second corrector to the setpoint signal in order to generate a control signal;
wherein the first and second correctors have different parameters in order to compensate for a behavior of the mechanism being dissymmetric in the first direction and in the second direction, and
wherein one of the first and second correctors:
is associated with one among the first and second directions in which the mechanism reacts slower than in the other direction, and
is a faster corrector than the other corrector.
