Explain what PID autotuning does and when you would use it?

• A. It automatically determines initial proportional, integral, and derivative settings based on system response; used during commissioning or after major process changes to accelerate and stabilize tuning.
• B. It manually sets PID by guesswork.
• C. It tunes only the P parameter while ignoring I and D.
• D. It is used only for temperature sensors.

Answer: (C)
