Q

Which of the following statements expresses the function of proportional-plus-reset action?

🔍 Key Concepts

• Proportional control – output is proportional to the error (difference between setpoint and measured value) • Reset (integral) action – gradually removes steady-state error (offset) over time • Difference between rate (derivative) action and reset (integral) action in a controller

💭 Think About

• Ask yourself: When a controller has only proportional action, what happens to the error (offset) when the load changes and then stays steady? • How does adding reset/integral action change the long‑term error after a disturbance – does it stay, slowly disappear, or react only to rapid changes? • Which option is actually describing derivative (rate) action instead of reset action?

✅ Before You Answer

• Be sure which term means eliminating steady‑state offset: proportional, reset (integral), or rate (derivative)? • Check which choice is talking about rate of change – that usually belongs to derivative action, not proportional‑plus‑reset. • Confirm which statement describes a controller that can hold the process at setpoint under varying load conditions without a permanent offset.
