ams.core.service.MinDurInit

class ams.core.service.MinDurInit(u: Callable, td: Callable, tau0: Callable, ug0: Callable, match: int, name: str = None, tex_name: str = None, unit: str = None, info: str = None, vtype: Type = None, no_parse: bool = False, sparse: bool = False)

Build the initial-state coefficient matrix for UC minimum on/off duration. Pairs with MinDur to close the boundary the interior window-sum cannot reach: a unit's history before t=1 decides how many leading periods are locked.

Returns M[g, t] = 1 iff t < L[g] and ug0[g] == match (else 0), where:

L[g] = max(0, ceil((td[g] - tau0[g]) / Δt))

Concrete usage in UC:

• on-side (must stay ON from history): td=td1, tau0=ton0, match=1; paired with constraint M * (1 - ugd) <= 0.

• off-side (must stay OFF from history): td=td2, tau0=toff0, match=0; paired with constraint M * ugd <= 0.

Note: like MinDur, inherits the parameter-plumbing of NumOpDual only; fun/rfun are unused. Extra inputs (tau0, ug0, match) are stored as plain attributes and consulted by .v.

Parameters:

uCallable

Var with horizon — used for shape (n_gen, n_ts) only.

tdCallable

RParam — minimum on/off duration (td1 or td2).

tau0Callable

RParam — initial elapsed on/off time (ton0 or toff0).

ug0Callable

RParam — initial commit status (ug); flattened to 1D before comparison.

matchint

Gate value: 1 for on-side, 0 for off-side.
