🔍 Key Concepts

• final control element motion vs. error (deviation from set point) • Difference between proportional, integral, and derivative actions in control systems • How a simple on/off (two-position) controller behaves compared to a linear response

💭 Think About

• Ask yourself: which option describes a control where the speed of movement of the valve/damper/etc. increases steadily as the error from set point gets larger? • Think about what derivative and integral actually act on: are they based on the size of the error, the time the error exists, or how fast the error is changing? • Which mode would give only full on or full off motion, with no in-between speed, and can you rule that one out first?

✅ Before You Answer

• Verify which mode relates to linear proportionality to the present error (deviation) itself, not its rate of change or its accumulation over time. • Confirm that two-position control cannot produce a continuously varying speed—only two states. • Check that the correct choice directly links the speed of the final element to the instantaneous deviation from set point.
