The Real Time Dynamics Toolbox is a novel approach to the implementation of
block / signal based schematics, commonly used in control engineering and signal
processing, for real time usage (like Real-Time Workshop® or Scicos Code
Generation). It is suitable for implementing time discrete signal processing
algorithms, like one would do in Scicos or Simulink, within Scilab scripts
(Matlab like) by using toolbox functions in order to set-up a description of the
schematic. This way, well structured code can be achieved, whereby i.e. the
filter design could be included nearby the implementation for better review.
Additionally, functional and object orientated design schemes can be realised.
The latter feature enables the possibility to implement reusable parametrised
sub-schematics that may also change in its structure based on parametrisation.
The actual generation process of the implementation (which would be equivalent
to code generation in Scicos/Simulink) does not involve source code generation /
compilation steps and therefore does not rely on having compilers for the target
system to be installed on the development computer. Scilab along with the
installed toolbox is sufficient for implementing.
Further, along with the remote control interface and the ability to implement
state machines, to run different simulations in threads and to include
Scilab-Code as computational functions (S-function like), ORTD is also ideally
suited for laboratory automation. The ability to replace sub-schematics with new
implementations and parameters during runtime removes the effort of restarting
the main real time program.
ORTD can be easily integrated into other simulation frameworks e.g. Scicos or
used within other software by including a shared library.
The latestest versions include highly advanced features like
* Online replacement of sub-controllers; Yes, can can exchange wires and blocks
during the controller is running (modules/nested)
* State machines (modules/nested)
* Simulations running in threads (modules/nested)
* Mathematical formula parsing (modules/muparser)
* Vectors handling blocks (modules/basic_ldblocks)
* Calling Scilab from the simulation (modules/scilab)
* Remote control interface (modules/rt_server)
* Starting external processes (modules/ext\_process)
* Timer for simulations running in threads (pending) (modules/synchronisation)
* Scicos to ORTD block wrapper (modules/scicos_blocks)

UPDATES
24.9.2011 - new version 0.99f
4.11.2011 - new version 0.99g
16.11.2011 - Added some slides that serve as an introduction.
28.3.2012 - Updated the slides.
8.6.2012 - Updated the slides.
13.7.2012: ORTD compiles on the beaglebone and potentially other ARM devices.
Installation instructions are found in the README.
13.7.2012: There won't be realease any more. Instead the svn-version in the
"trunk"-folder will always be in a production state and include at the
same time the latest features. Development is done within branches and then
merged to the "trunk"-folder.
The newest version is found in subversion and can be installed by a graphical
userinterface via pasting
wget openrtdynamics.sf.net/getit.sh -O - | bash
into your Terminal on Linux (See http://openrtdynamics.sourceforge.net/bigace/public/index.php?cmd=smarty&id=6_len).
Alternatively, use an automatically generated package:
http://openrtdynamics.svn.sourceforge.net/viewvc/openrtdynamics/trunk/?view=tar
and follow the instructions in the README-file.
