Patent ID: 8918291

Claim:
A method for monitoring an actuator equipped with a no-back device, comprising: detecting reversal of a direction of movement of the actuator; storing in memory, when reversal of the direction of movement of the actuator is detected, a current angular position as a reference angular position of the actuator; determining a value representative of mechanical work produced by the actuator; comparing the value representative of the mechanical work produced with ranges of values; and detecting dysfunctioning of the no-back device by the comparing, wherein detection of dysfunctioning is temporarily inhibited upon detecting reversal of the direction of movement of the actuator and as long as the angular displacement of the actuator remains within free play of the no-back device, and wherein a subsequent current angular position is compared with the reference angular position stored in the memory to determine when the angular displacement of the actuator remains within the free play of the no-back device.
