Abstract: An electronic processing circuit 17 compares digital signals representing the position of a number of mutually connected control members to the contents of an electronic memory 18. On detecting a difference indicating the displacement of the position of one of the control members, the circuit 17 actuates those motors of motors 4, 5, 6 which are associated with the non-actuated control members in order to make them folllow the displacement. Excessive displacements indicating a fault are shown on an indicator 19.

Abstract: Control system, including a plurality of control members electrically coupled with one another and with a device to be controlled, particularly for controlling a ship's equipment, wherein each control member is provided with a potentiometer for generating electrical control signals, and each control member can be coupled with a follow-up member, the control member and the follow-up member being connected to a differential amplifier determining a signal which is characteristic of a difference in position of each control member and each follow-up member and forming control signals for the follow-up members, the follow-up members preferably being formed by a setting motor and a potentiometer coupled with the same.
