TRIM, LINEARIZATION, EIGENVALUES AND 64-BIT

A major new upgrade to the JSBSim S-Function project will be released very soon - a trim and linearization function! The foundation for the trim and linearization script was originally part of the Aerosim blockset and was written by Marius Niculescu of U-Dynamics. He generously allowed me to incorporate it into the project.

Now when a model is selected to run in the GUI, it can be trimmed to the flight condition and control inputs that are in the GUI fields. After trimming it will be linearized with decoupled state-space matrices and eigen-values printed to the workspace. The new trimmed states and control inputs are then available for use in subsequent

There is also a win64 compiled mex file in the project ( I hope to have a Mac OS version in the near future as well.)

I am waiting on some feedback and a few documentation changes before I release the project, but it won't be long.

Best Regards,

Brian Mills

Here is the link to the latest project release
http://dl.dropbox.com/u/5284957/JSBSimSFunc_release.zip

The new release features win64 compiled versions of the SFunctions and the Trim and Linearization functions. Unfortunately, the documentation is still not finished, but there are some basic instructions provided in the GUI Help and the Readme file. I hope to have the documentation finished for the next release. I also hope to have a Mac OS version that will be compiled by Agostino included at some point, as well as a Linux OS version.

Thanks for downloading!

Brian

I have completed a major update to the project with numerous bug fixes and a completely new file structure. Please download it here http://dl.dropbox.com/u/5284957/JSBSimSFunction.zip.

I think you will find that it is a major improvement over any previous version of the project. Please feel free to give me any feedback.

Cheers

Brian

Please download the latest release here: http://dl.dropbox.com/u/5284957/JSBSim_MATLAB_release.zip

It is still quite "beta" and because I do not have a 32-bit machine at the moment, there are only win64 versions of the MEX files compiled. I hope to have a release soon that will include 32-bit versions of the MEX files.

I want to work on the formation control for the landscape coverage by blimps. would you please what is your suggestion to select a good flight dynamic simulator and visualization tools?

Hi,

 

I'm a 3rd year Aerospace Engineering student and am doing a project entitled, 'Simulink 3D Animation for Teaching Dynamics'.

The aim of the project is to create a flight simulator using Simulink and Simulink 3D Animation which also gives graphical views of the aircraft responses to joystick inputs.

 

I've downloaded what appears to be the latest version of the SFunction but am having trouble making it work..

Also I have no idea where to start with the project.

 

Any help would be greatly appreciated..

Thanks

What exactly are you having trouble with?  What type of machine are you running it on? Have you followed the steps in the README file? Also, don't forget to read the JSBSim SFunction User's Guide and check out http://jsbsim.sourceforge.net/matlab.html as well for some more information. 

 

With the addition of a simple joystick input block (which I could send you) you can do everything that you describe for your project. Good luck and if you need more help just let me know!
