Autopilot

An autopilot controls the steering gear of a vessel to keep it on course. There are two types of control methods. One is called single-loop control and uses torque motors or the like, and the other is called two-loop control which uses solenoid valves or servo-cylinders as actuators. The actuator selection depends on what type of steering gear is used.

– Follow up (FU) controlThis is servo control which drives the rudder until the command angle of the autopilot is equals to the feedback angle from the steering gear. FU control is divided into automatic steering (AUTO) mode, manual steering (HAND) mode, remote control (RC) mode, and NAVI mode, which is especially provided for track control. These modes can be selected with the MODE switch.– Non-follow-up (NFU) controlThis is open loop control and it is occasionally used in emergencies. It directly drives the actuators of the steering gear. This control is well known as emergency steering and selectable when SYSTEM switch is in the NFU position.
