get_piecewise_constant_constraints

(function from pyomo.contrib.mpc.modeling.constraints)

pyomo.contrib.mpc.modeling.constraints.get_piecewise_constant_constraints(inputs, time, sample_points, use_next=True)[source]

Returns an IndexedConstraint that constrains the provided variables to be constant between the provided sample points

Parameters:

  • inputs (list of variables) – Time-indexed variables that will be constrained piecewise constant

  • time (Set) – Set of points at which provided variables will be constrained

  • sample_points (List of floats) – Points at which “constant constraints” will be omitted; these are points at which the provided variables may vary.

  • use_next (Bool (default True)) – Whether the next time point will be used in the constant constraint at each point in time. Otherwise, the previous time point is used.

Returns:

A RangeSet indexing the list of variables provided and a Constraint indexed by the product of this RangeSet and time.

Return type:

Set, IndexedConstraint
