The present invention relates to a motorized electric control device provided with a joystick (14), characterized in that it comprises two electrtic torque motors (4, 5) whose axes of rotation are at right angles to one another, two forks (9, 10) coupled at one end to the respective torque motor shafts and offset relative to said shafts, the joystick being mounted for pivoting in relation to the point of intersection of the axes of rotation of the torque motors, resilient means for returning the joystick to a vertical position, rotary potentiometers (22) whose axis of rotation is fixed to the other ends of the forks (9, 10) and whose electric outputs constitute the control outputs of the device, and an electric circuit (30) connected to the outputs of the potentiometers and to the electric inputs of the torque motors in order to produce a resistant torque opposite and proportional to the inclination of the joystick (14) in the vertical position.

A control system including a motorized electric control device, said motorized electric control device comprising: a pair of electric torque motors (4, 5; 34, 35), each of said torque motors having a respective shaft, and each of said shafts having an axis of rotation which is perpendicular to the other, thereby forming a point of intersection between the axes of said shafts; a pair of forks (9, 10), each of said forks being coupled at one end thereof to a different one of said shafts, and each of said forks being disposed offset relative to its associated shaft; a joystick (14) mounted such that it passes through said forks and such that it pivots in relation to the point of intersection of the axes of rotation of the shafts; resilient means (29) for returning the joystick to a vertical position; a pair of rotary potentiometers (22; 36, 37), each of said forks being coupled at the other end thereof to a different one of said potentiometers; and an electric circuit (30) connected to the potentiometers and to the electric torque motors such that said torque motors receive a current which creates a resistant torque opposite and directly proportional to their angular displacement relative to the vertical position of said joystick (14).
