Quick PID Tuning Basics
該当する場合
Use this guide for transparent first gains when you already have a rough process model or step-test estimates.
使うツール
P, I, and D starting gains from process lag and damping targets—loop screening; validate on the real plant.
PID Tuning Helper を開く →手順
- 1Identify process gain, time constant, and dead time from a defensible step or bump test.
- 2Choose a tuning rule appropriate to loop speed and robustness needs.
- 3Compute P, I, and D contributions and check for unreasonable gain or rate limits.
- 4Simulate or test in manual-friendly conditions before full automation.
- 5Iterate after observing noise, valve stiction, and setpoint changes.
例
- Flow loop with fast dynamics vs temperature loop with minutes of lag.
- Level loop where integrating behavior dominates.
避けること
- Tuning without understanding whether the loop is integrating.
- Using aggressive ZN gains on noisy signals.
- Ignoring output limits that invalidate linear predictions.

よくある質問
Does this auto-tune online?
No. It helps compute suggested gains from your entered model.
Cascade loops?
Tune inner fast loops first; this guide targets single-loop screening.
