added steady state to delta derivation

All the engine model inputs are deltas so a transfer function
to has been found that takes a steady state input and produces
a delta output.  Then common control systems which produce
a steady state control can be used.
eliminated use of Bloques for TikZ directly

All uses of Bloques, a library for creating control system
diagrams, has been removed.  It did produce some nice graphics
but it was inflexible and difficult to fine tune.
Creating control system diagrams directly in TikZ along with
styles produces better results and is easier to maintain.
added COPYING and README
documented delta to steady state conversion

The transfer function to convert delta values to
steady state has been derived and documented.
more work on the engine model

Still trying to sort out the engine model so it can
be used with a controller.
engine model with no control working

With the torque input is set to zero a transfer function
representing the engine model can be constructed.
This should be suitable for building control systems
using pole placements or other methods.
added abstract, minor cleanups
converted ignition points to time in model description

Previously the engine model response with no control
showed rpm versus ignition points.  But this did not
indicate how much time it took to stabilize.
A conversion was found to plot these with time.
normalization corrections for engine model

Corrections to normalize the engine model have been found
which will accept a step input and produce a response near one.
changed the title
shifting/scaling unnecessary?

It appears that the shift and scaling of the model so
that it accommodates a step function may be unnecessary.
Systems designed from specs have no such requirement.
created good examples of scaled/shifted model

The description of the engine response with a scaled/shifted
has been added.  The response should serve as a good basis
for building controllers and comparing the results.
cleaned up diagram and some text, minor
Direct Design working, major cleanup of Octave files

The first model has been built using Direct Design.
And it is a significant improvement compared to no control.

The Octave files used for generating the plots have been
cleaned up and their names made more consistent.
finished documentation of Direct Design method

The Direct Design method has been documented which
includes the steps needed to calculate D(z) and K.
general cleanup, added contents, changed title page

The title page has been changed to only include itself
and the abstract.  On the next page is the contents and
after that is the body of the text.  Before the body
started with the title page and there was no contents.
changed print -color -deps2 to -depsc2
now make in paper/ will also make ../octave
moved pdf to build branch
regulator system is wrong size?

An attempt was made to construct a regulator system
(Control Law, Full Order) however the sizes do not match.
The system (Gz) has one input and one output however the
feedback (K), as produced using Ackermann's Formula
has three inputs for the 3rd order system.
Is this a case where the other values must be estimated?
