METHOD FOR CONTROLLING AN ACTUATOR AND ASSOCIATED CONTROL DEVICE

METHOD FOR CONTROLLING AN ACTUATOR AND ASSOCIATED CONTROL DEVICE

The present invention relates to a method for controlling an actuator (4) comprising a mobile element (60), the method comprising steps of receiving a set-point signal and two position-measurement signals (A, B) of the mobile element (60) acquired by different position sensors (7), calculating a dev...

description The present invention relates to a method for controlling an actuator (4) comprising a mobile element (60), the method comprising steps of receiving a set-point signal and two position-measurement signals (A, B) of the mobile element (60) acquired by different position sensors (7), calculating a deviation between the two position-measurement signals (A, B), generating (102) a control signal (S) for controlling a movement of the mobile element (60) on the basis of the set-point signal (E) and at least one of the position-measurement signals (A, B), the method being characterised in that when the deviation between the position-measurement signals (A, B) crosses (201) a predetermined threshold, said method comprises the following steps: setting (202) the control signal (S) to a constant value so as to immobilise the mobile element (60), for each of the two measurement signals (A, B), calculating an interval of positions associated with the measurement signal (A), and detecting an output of the value of a measurement signal (A) outside the associated interval while the control signal (S) is set to the constant value.
