!!! Feedforward Variables (FVs)

Feedforward variables are model coefficients that change to fit process data.  These parameters can change the behavior and structure of the model.  A parameter is indicated as a feedforward variable by including a line in the INFO file with an ''F'' and the variable name, separated by a comma.

''F, model.parameter''

!!! Fixed Values (FVs)

Fixed Values are model coefficients that change to fit process data.  These parameters can change the behavior and structure of the model.  A parameter is indicated as a fixed value or feedforward variable by including a line in the INFO file with an ''F'' and the variable name, separated by a comma.

-> ''F, model.parameter''

If using either the MATLAB or Python interface, fixed values can also be declared with the apm_info function as:

-> ''apm_info(server,app,'FV','{parameter_name}')

Feedforward variables
are model coefficients that change to fit process data.  These parameters can change the behavior and structure of the model.  A parameter is indicated as a feedforward variable by including a line in the INFO file with an ''F'' and the variable name, separated by a comma.

''F, file.model.parameter''

For time-varying simulations, the FVs
are constant over the time horizon.

!!!! Manipulated Variables

Manipulated variables are decision variables for an estimator or controller.  These decision variables are adjusted by the optimizer to minimize an objective function.  A parameter is indicated as a manipulated variable by including a line in the INFO file with an ''M'' and
the parameter name, separated by a comma.

''M, file.model.parameter''

For time-varying simulations, the MVs
change over the time horizon.

!!! State Variables (SVs)

States
are model variables that may be measured or are of special interest for observation.  A variable is indicated as a state by including a line in the INFO file with an ''S'' and the variable name, separated by a comma.

''S, file.model.variable''

For time-varying simulations
, the SVs change over the time horizon.

!!! Controlled Variables (CVs)

Controlled variables
are model variables that are included in the objective of a controller or optimizer.  These variables are controlled to a range, maximized, or minimized.  Controlled variables may also be measured values that are included for data reconciliation.  A variable is indicated as controlled by including a line in the INFO file with a ''C'' and the variable name, separated by a comma.

''C, file.model.parameter''

For time-varying simulations, the CVs
change over the time horizon.
