  • Arrangement for monitoring a rudder control system
    Patent number: 4374423
    Abstract: Signals from a rudder position setting control and from a rudder position sensor constitute the only electrical information sources needed for operating a monitoring system for a rudder control that produces an alarm when the rudder control does not function effectively. The difference between the desired rudder setting and the actual rudder position, generated by a differential amplifier, is fed to a bi-directional limit circuit and a differentiating circuit is used to generate a signal corresponding to the rate of change of rudder position, which signal is likewise provided to a bi-directional limit circuit.
