Abstract:
The invention proposes a method for characterizing the amplitude (AS) of play (S(t)) in an electromechanical actuator ( 10 ), the electromechanical actuator comprising an electric motor ( 11 ) and a movable element ( 1 ) that is able to be moved by the motor, the actuator ( 10 ) comprising an upstream sensor ( 41 ) suitable for measuring a position (Xl(t)) of the motor and a downstream sensor ( 42 ) suitable for measuring a position (X2(t)) of the movable element, and a force sensor ( 43 ) suitable for measuring a load (Fl(t)) applied to the movable element, the method comprising steps of: (El) measuring the position (Xl(t)) of the motor, the position (X2(t)) of the movable element and the load (Fl(t)) applied to the movable element using the three sensors; (E2) on the basis of a computer model of the actuator and of the measured position (Xl(t)) of the motor, of the measured position (X2(t)) of the movable element and of the measured load (Fl(t)) applied to the movable element, estimating a value of the amount of mechanical play (S(t)) using a state observer and considering the play (S(t)) to be a state component; and (E3) determining the amplitude (AS) of the play from a set of values of the dynamic variable, which values are obtained in the preceding step at various times (t).

Claim (Index 15):
The method according to  claim 14  in combination, wherein the amplitude of the play (\u0394S) is calculated as follows: \u0394 \ue89e \ue89e S = \u2211 k = 1 p \ue89e \ue89e S p \ue8a0 ( k ) p - \u2211 k = 1 n \ue89e \ue89e S n \ue8a0 ( k ) n where S p \ue8a0 ( k ) = { S \ue8a0 ( k ) \ue89e / \ue89e S \ue8a0 ( k ) \u2265 max \ue8a0 [ S \ue8a0 ( k ) ] + min \ue8a0 [ S \ue8a0 ( k ) ] 2 } S n \ue8a0 ( k ) = { S \ue8a0 ( k ) \ue89e / \ue89e S \ue8a0 ( k ) < max \ue8a0 [ S \ue8a0 ( k ) ] + min \ue8a0 [ S \ue8a0 ( k ) ] 2 }
