Abstract:
Methods of compensating for play and for initializing a position encoder in an actuation system ( 2 ) including an actuated system ( 8 ) comprising an elastic element, and an actuator ( 4 ) with a stepper motor ( 12 ) having at least one electrical phase.

Claim (Index 29):
A method of compensating for play in an actuation system ( 2 ) including an actuated system ( 8 ) comprising an elastic element, and an actuator ( 4 ) with a stepper motor ( 12 ) having at least one electrical phase, the method comprising:\n supplying by means of a current controller said at least one electrical phase with a first limited phase current configured to drive the rotor of the stepper motor in a first direction (X+), said limited phase current having an amplitude inferior to an operational phase current needed to drive the rotor in normal load operation for actuation of the actuated system in said first direction, detecting a loss of steps of the stepper motor in said first direction and determining therefrom a first end of mechanical play position, driving with a second limited phase current the rotor of the stepper motor in a second direction (X\u2212) opposite to the first direction, said second limited phase current having an amplitude inferior to an operational phase current needed to drive the rotor in normal load operation for actuation of the actuated system in the second direction, detecting a loss of steps of the stepper motor in said second direction and determining therefrom a second end of mechanical play position, and compensating for mechanical play in the actuation system based on the first and second ends of mechanical play positions.
