1. A method for adjusting an angular position of a wheel, the wheel being connected to at least one hydraulic cylinder controlled by a servo valve, the method comprising:
a step to determine an angular difference between a measurement of the angular position and a setpoint angular position,
a first proportional correction step in order to determine a first current from an angular deviation,
a second integral correction step in order to determine a second current from the angular deviation,
an addition step of the first current and the second current in order to determine a control current of the servo valve, wherein
the second integral adjustment step comprises a sub-step limiting the second current according to a parametric law, the parametric law imposing a second current of zero value when the angular deviation is less, in absolute value, than a first determined angular threshold.
