🔍 Key Concepts

• Follow-up steering systems: how feedback from the rudder position reduces the error between commanded angle and actual angle • Rudder angle error: difference between helm command angle and actual rudder angle, and what happens as this error gets smaller • Hydraulic pump tilt box (or stroke) control: how the control signal changes as the system nears the desired position

💭 Think About

• Think about what a closed-loop control system does as the actual position gets closer to the commanded position: does the correcting signal grow or shrink? • In a follow-up system, what is the purpose of the feedback from the rudder angle transmitter or follow-up linkage? How does it affect the control signal when the rudder is almost on command? • If the system kept increasing its control signal as the rudder reached the ordered angle, what would happen to the rudder motion?

✅ Before You Answer

• Verify how a follow-up mechanism behaves: it should act to reduce rudder angle error toward zero. • Consider whether the control signal to the pump tilt box controls should be larger or smaller when the rudder is nearly on the ordered angle. • Check which choice, if true, would logically stop the rudder at the ordered angle rather than overshooting it.
