About the marine rudder is a flat plate or wing structure with small aspect ratio (that is, the ratio of rudder height to rudder width). When the rudder rotates, the force acting on the rudder blade can be divided into rudder resistance and rudder lift. The rudder resistance is in the direction of fluid flow (that is, the ship's sailing direction), and the rudder lift is perpendicular to the flow direction of fluid. The rudder lift will produce a rudder moment relative to the midship, making the ship turn.

The traditional rudder angle transmitting and receiving display devices are all heavy and backward AC or DC selsyn with analog pointer display. The readings are not direct and are easy to generate errors. When other devices (such as digital devices such as autopilot) need to access this signal, they need to be digitally processed, which is extremely inconvenient and has low accuracy, affecting the overall control performance of the system.

After hearing the order of rudder angle issued by the officer on duty, the helmsman shall immediately repeat and quickly and accurately turn the steering wheel to the rudder angle ordered, pay attention to the actual deflection and angle of the rudder blade indicated by the rudder angle indicator, and report in time when the rudder blade reaches the required angle. Before the officer on duty issues a new rudder order, the helmsman shall not change the position of the rudder at will. The method of steering according to rudder angle is usually adopted when ships enter or leave the port, berthing or unberthing, and take avoidance measures at sea.

Under the steering control system, there is a rudder angle adjuster, two adjusting knobs, one for left and right deflection, and one for angle adjustment. This adjustment rule not only considers that the yaw angle is large, the yaw angle should be large, but also considers that the yaw rate is large, and the yaw angle should also be increased. The introduction of differential link can speed up the rudder feeding speed, better overcome the ship's turning inertia, improve the stability of the system and the ship's turning inertia, and improve the stability and heading accuracy of the system.
