Enum ControllerOutcome 

pub enum ControllerOutcome {
    InDeadband,
    AtLimit,
    Closest,
    Insensitive,
    Hunting,
    Unfinished,
}

How one controller finished.

Variants

InDeadband

The controlled quantity is inside the deadband. The success case.

AtLimit

The controller asked for a ratio or angle outside what this changer can produce at all, and is sitting at whichever end is nearest.

Closest

The best position the table offers, with the target still outside the deadband — the discrete grid has nothing closer.

Common rather than exceptional: a tap moves in finite steps, so a deadband narrower than one step’s worth of effect can be unreachable from every position. ENTSO-E’s own PST_PhaseTapChangerLinear_Type2 asks for zero flow within 5e-4 pu on a shifter whose closest position leaves 0.11 pu, and calling that InDeadband — as an earlier draft did — reports success at a flow 200 times the tolerance.

Insensitive

|∂target/∂tap| is below MIN_SENSITIVITY; this controller cannot move its own controlled quantity.

Hunting

Reversed direction MAX_DIRECTION_CHANGES times without landing inside the deadband — two positions straddle the target and neither is acceptable.

Unfinished

The run ended (budget, or another loop failing) before this controller settled.
