🔍 Key Concepts

• Deadband in a follow‑up steering system is the rudder angle range where no corrective signal is sent (neither relay is energized). • In the graph, the deadband is shown by the vertical arrow between the ‘Port relay off’ and ‘Starboard relay off’ levels, expressed first in translator voltage (Vp) and then converted to rudder angle. • Control stability is judged by what happens to the oscillations over time: a stable system’s swings decrease, an unstable system’s swings grow, and a marginal system’s swings stay about the same.

💭 Think About

• From the figure, between which two horizontal lines is the deadband arrow drawn, and what is the voltage difference (ΔVp) between them? How many rudder degrees correspond to that ΔVp using the Vp-to-rudder scale? • Look at the rudder response curve after the initial command: do the successive overshoots get larger, smaller, or stay about the same as time increases? What does that say about inherent stability? • Which answer choice matches BOTH the deadband you read from the Vp scale (after converting to degrees) and your conclusion about whether the oscillations show a stable or unstable system?

✅ Before You Answer

• Double‑check the Vp-to-rudder angle scale on the left: how many degrees of rudder correspond to the full 0–10 Vp range? • Confirm that you are using the relay OFF levels (not relay ON) to measure the deadband, as indicated by the arrow on the right side of the graph. • Before choosing, verify that your option’s statement about stability vs. instability matches the observed trend of the overshoot amplitudes over time.
