Appendix 6.1: Control System Input Description
==============================================
This appendix contains a description of the |SAS| input block
assigned to the control system model.
Input Block Structure
---------------------
The input block structure is identical to the standard |SAS|
input block structure in all but one respect. A new card format known as
a signal card has been introduced. These cards immediately follow the
block identifier card and precede the standard data cards. The ordering
of the different card types is depicted in the diagram below.

Block Identifier Card
---------------------
Block identifier cards are described in :numref:`section-A2.2`. For the control
system input block the number is 5 and the block name is INCONT.

A signal card is used to define a signal in the user's control block diagram.
There are four signal types:
measured, demand, block and control. Each signal must be assigned a
unique signal identification number using the ISIG field. The value of
ISIG must lie between 1 and 998, or between 1000 and 10000. The remaining variables that are used to
define control system signals are defined in :numref:`table-A6.1-1`.

Measured Signal
~~~~~~~~~~~~~~~
A measured signal makes available to the block diagram the present value
of a referenced |SAS| variable. The correspondence between the
variable that is referenced and the signal card data field values is
given in :numref:`table-A6.1-3`. Note that all measured signals have a JTYPE value
between -50 and -89 or between -101 and -136.
Demand Signal
~~~~~~~~~~~~~
A demand signal makes available to the block diagram the product of the
current value of a time dependent function defined by the user through a
demand table and an initial condition value. A demand table is a set of (``CTLTAB``, ``CTLTIM``)
ordered pairs supplied by the user in the format of :numref:`table-A6.1-4`.
The code obtains the demand signal value by linearly
interpolating among the table entries using the current time. The
initial value is obtained as described in :numref:`section-6.4`. The
correspondence between the demand table and the signal card data fields
is given in :numref:`table-A6.1-3`.
Note that a :ref:`demand signal <DemandTable>` has a JTYPE value of -90.
Block Signal
~~~~~~~~~~~~
A block signal makes available to the block diagram the value at the
output of a block. The correspondence between the block characteristics
and the signal card data fields is given in :numref:`table-A6.1-3`. Note that all
block signals have a JTYPE value between 1 and 23. A measured, demand or
block signal can be used as an input to a block by specifying on the
block's signal definition card the signal identification number assigned
to the input signal. The signals input to each block type are combined
according to the mathematical expressions given in :numref:`table-A6.1-2`.

Control Signals
~~~~~~~~~~~~~~~
A control signal is used to set the value of a |SAS| variable
equal to the value of a block signal. The correspondence between the
block signal and the |SAS| variable and the signal card data
fields is given in :numref:`table-A6.1-3`. Note that all control signals have a
JTYPE value between -1 and -10.
End of Signals
~~~~~~~~~~~~~~
A sequence of signal definition cards is delimited by a signal card with
the ISIG field entry equal to '999'.
This card also contains flags for the binary output file print interval
and control of the stead state solution finder. First, the absolute
value of the JTYPE field for the 999 card is sets the print interval for
control system results output to the binary output file CONTROL.dat.
Second, the J1SIG field is used to determine whether the steady state
solution finder is to be used. An entry of '1' indicates that the steady
state solution finder is to be used, while any other entry in this field
causes the solution finder to be bypassed. (A discussion of the initial
condition option is given in :numref:`section-6.4`). Finally, the J2SIG field
allows the user to control the amount of steady state output generated.
An entry of '1' produces an extended output for trouble shooting
purposes, while any other entry produces a standard output.
The JTYPE field is also used to generate an extended printout during the
transient for debug purposes. The debug is generated by setting the
JTYPE field of the 999 card to a negative value. The printout begins at
the time specified on the F1SIG field.

Data Cards
----------
.. code-block:: fortran
form = "(2I6,5F12.0)"
read(*,form) LOC, N, VAR1, VAR2, VAR3, VAR4, VAR5
A data card appearing in the control system block has a format identical
to the standard |SAS| data card used in floating-point input blocks
and is processed in the same way. This means that :ref:`free-formatted input<rubric-FreeFormattedInput>` may
be used as an alternative to the fixed format shown above.
Data cards are used to construct demand tables, function generator
tables and to supply solution convergence parameters. These quantities and
their storage locations are defined in :numref:`table-A6.1-4`.

Sample Input
------------
:numref:`INCONT-listing-1` and :numref:`INCONT-listing-2` show examples of input for the control system.
The first listing utilizes a weighted average of the liquid temperature in four compressible volumes to control a valve and additional reactivity. (Note that 0.0245+0.7026+0.2435+0.0294 = 1.) The second listing shows how to access core channel state variables and apply scale and offset parameters. It also demonstrates the calculation of a simple average.
