Abstract:
1. A monitoring method for monitoring a servo-control loop ( 3 ) of an actuator system ( 2 ) for actuating variable-geometry components of a turbojet, the actuator system ( 2 ) comprising at least a servovalve ( 25 ), and first and second actuators ( 21 , 22 ), said method comprising: an estimation step E an evaluation step E an evaluation step E a detection and location step E wherein, during the estimation step E a category of parameters representative of positions VSV a category of parameters representative of coefficients of autoregressive models used for predicting actuator positions as a function of a control current iCMD of the servovalve ( a category of parameters representative of the control current iCMD of the servovalve (
