<pre class="comment">AUTOGUI S-function for making a simple PID GUI
When the model autotunerPID.mdl is run, this S-function create a panel
which closer resemble the layout of a typical real industrial autotuner
(at least in the control options).
The upper part of the GUI is used to interact with the control system,
by changing the set-point value and by reading the value of the process
value and the control variable. Moreover when used in MANUAL mode the
control variable is under the direct control of the user. The
parameters area shows the parameter of the PID which can be changed
online (except for the derivative weight c which is fixed to 0.
The last two areas allow to select the operating mode (AUTO/MANUAL) and
the autotuning method, split in the selection of the identification
method, the selection of the tuning method and the selection of the
regulator structure.
Everything started looking at PENDAN, an S-function for making pendulum
animation
