This collection of Matlab(r) files can be used for design and simulation of
control systems based on multi-layer perceptron type neural networks. Tools
are provided for:

o Direct inverse control.
o Control based on instantaneous linearization.
o Optimal control.
o Control by feedback linearization.
o Nonlinear generalized predictive control.
o Internal model control.
o Feedforward control.

A number of simple demonstration programs have been implemented to illustrate
most of the concepts. Run these to get an idea about what the toolkit has to
offer. Be careful with the demos, however. Due to problems with local
minima the results can vary quite a lot between to runs of the same demo.

In the current directory you should be able to find a brief manual in
postscript format. Start by printing out this and study the release notes
carefully. The release notes have also been witten in a file in this
directory ("RELEASE").

The different functions do not contain "on-line" help regading their use.
Instead you should study the text files 'Fblin', 'Feedforw', 'Imc', 'Instlin',
'Inverse', 'Npc', 'Optim' for an on-line explanation of the different
concepts.

The functions have not been thoroughly tested and thus you are likely 
to encounter bugs every once in a while. However, I hope I have managed
to eliminate most of the bugs.

Enjoy!

Read the file "Contents.m" for a complete overview of the toolkit.

                             
DEMONSTRATION PROGRAMS:
In order to run the demos you must go to the directory "CTRLDEMO" (and this
directory must NOT be write protected!).

!!Notice that you may have to resize the GUI window with the mouse if you
cannot read all the text because the font size is too large compared to the
window size!!
