Re: [Jsbsim-matlab] JSBSim S-Function

[b m. <bri...@in...>]

I've been using modified Aerosim xml parsers to import JSBSim config files into Matlab for several years now.  The problem is that the parsers have not kept pace with changes in the JSBSim xml format.  They are in need of an overhaul and I can currently only import the old (v1.0?) format JSBSim files. The parsers are written as m-files.

What would be interesting is to see if a matlab m-file could be written that would "parse" a simulink model of say, a flight control subsystem, and produce a JSBSim compatible fcs xml file. If RTW workshop can turn a simulink model into code, then it seems like something could be written as an m-file to do this.  I've already written a Matlab GUI program that can produce a JSBSim FCS xml file, so some progress is already made on this.
