Mechanisms¶
- Process Control Tuning
- Its classic failure is integral windup: when the actuator saturates, the integral term keeps accumulating error it can't act on, so when the state finally moves the controller overcorrects violently and the system lurches or oscillates.
This sourceExplains integrator windup under actuator saturation, including accumulated integral action, large overshoot, and oscillatory recovery.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
