Adaptive feedback control of an optronic sight

An optronic sight for a motorized vehicle such as an aerial or marine vehicle propelled by a propeller or a tracked land vehicle, the optronic sight comprising:

• an aiming module configured to be moved about a first axis and a second axis not parallel to the first axis,
• means for moving the aiming module about the first and second axes,
• means for continuously measuring an angular data of the aiming module about the first and second axes;
• a feedback control loop, comprising:
• means for continuously measuring the acceleration of the aiming module according to three orthogonal directions of a space;
• and
• means for detecting at least one fundamental frequency of the vibratory disturbances generated by the operation of the motorized vehicle, the at least one fundamental frequency being obtained based on the output data of the acceleration measuring means;
• and
• an adaptive corrector configured to:
• continuously receive as input:
• said fundamental frequency;
• and
• a discrepancy between an angular setpoint value and said angular data;
• and
• output a movement setpoint value to the moving means.
