This is an era of automation where it is broadly defined as replacement of manual effort by electronic power in all degrees of automation. The possible faults stated earlier would be the earth fault or supply irregularity. If H (s) is the transfer function of the feedback path, then the transfer function of the feedback signal will be B (s) = C (s)H (s). It does make some sense! If electric, should be fed from own separate circuit supplied from a steering gear power circuit from a point within the steering gear compartment, or directly from switchboard busbars supplying that steering gear power circuit.That also, at a point on the switchboard adjacent to the supply to the steering gear power circuit; Means shall be provided in the steering gear compartment for disconnecting bridge control. Each remote steering gear control system power failure alarm. A Steering Gear is the equipment provided on ships to turn the ship to left (Port side) or to right (Starboard side) while in motion during sailing.
