Description
            This toolbox is aimed at computing a RST controler from a predictive controler
theory.

The RST equivalent controler is a monovariable controler (one input / one
output). There is no constraint management. The equivalent RST predictive
controler lets the user verify the stability and the robustness of the computed
controler.  

The algorithm used here is described in the book "La commande predictive" from
Patrick Boucher and Didier Dumur at chapter 3 page 51. ISBN : 9782710807025 (176
pages) edited in 1996.

The book is also available through google books via:
http://books.google.fr/books?id=LfUw9wKmDWEC&printsec=frontcover&hl=fr#v=onepage&q&f=false

In order to launch the predictive controler parameter tuning, execute the
predictive_gui() function.

This will open a simple window with the following parameters used for the
predictive controler computation:
- N1
- N2
- Nu
- Lambda

The System name, Time sampling and Stationary parameters describe the continuous
system to control:
- System name : string to qualify the linear continuous system to control
- Time sampling : time sampling in second
- Stationnary : time in second from which the system is considered as in
stationnary mode


Enjoy this toolbox and discover a first step into the predictive controler
theory. A demo is also available in the Demo tab of Scilab.

Answer from Samuel Gougeon -- January 6, 2018, 11:53:58 PM    
After the demo has been run once -- what opens a Xcos diagram --, pressing
"Generate" works.
Anyway, the packaging and the documentation of this module are unclear:

* some C gateway looks available in the sources, but is not compiled nor loaded in .start
* Demo: the user is prompted to create
  The file C:\demos\predictive_rst.zcos doesn't exist Do you want to create it?
  This is a definitely wrong proposal. The file should be created either in TMPDIR
  or SCIHOME.
* Help: as reported by Pierre on Bugzilla, either there is a missing internal
  initialization, or the documentation is too poor to start with.
  
If macros have just to be recompiled for Scilab 6: Alexandre, do not hesitate to set me as
a maintainer if you have no time to spend for this upgrade.
