JSBSim-Matlab

Matlab integration of JSBSim based on work of EliaTarasov

Compiled and tested on for Linux (Ubuntu).

Installation (JSBSim for MATLAB)

1. Type git submodule init and git submodule update - that will pull JSBSim submodule (note: consider updating to the latest JSBSIM from https://sourceforge.net/p/jsbsim/code/ci/master/tree/ ?)
2. Go to JSBSim directory and make sure you are on matlab_integration branch
3. Configure JSBSim for shared libraries: ./autogen.sh --enable-libraries --disable-static --enable-shared
4. Make JSBSim with shared libraries: make (it will take a moment)
5. Start Matlab (tested so far with 2014b) and navigate to the root directory of JSBSim-Matlab
6. In Matlab command line type: mex ./JSBSimMatlab/MexJSBSim.cpp ./JSBSimMatlab/JSBSimInterface.cpp -I./JSBSim/src -L./JSBSim/src/.libs -lJSBSim
7. Now you can run for example test1.m or test_c172_cruise_8K.m or simply call set/get handles in your own script

Installation (JSBSim for Simulink)

1. Do steps 1-5 as in the previous case
2. In Matlab command line type: mex -v ./JSBSimMatlab/JSBSim_SFunction.cpp ./JSBSimMatlab/JSBSimInterface.cpp -I./JSBSim/src -L./JSBSim/src/.libs -lJSBSim It will compile and output (on 64buit machines) JSBSim_SFunction.mexa64
3. Now start JSBSim_GUI.m - it will open a GUI that you need to use
4. In the GUI first click on Load Model (it will load the Simulink model with JSBSim S-function block). You have to do this even if your Simulink model is already loaded
5. In the GUI type into the aircraft model name c172x
6. In the GUI click on Initialize Model It should output something like JSBSim Flight Dynamics Model v1.0 Sep 6 2016 17:16:47[JSBSim-ML v2.0]JSBSim startup beginning ...
7. Now you can go to Simulink and run the simulation. You should get output like JSBSim S-Function is initializing... then lots of text and then 'c172x' Aircraft File has been successfully loaded! Simulation completed. That means that the model was loaded properly into JSBSim engine.
8. you can examine tout and xout variables - xout has 12 states ([u-fps v-fps w-fps p-radsec q-radsec r-radsec h-sl-ft long-gc-deg lat-gc-deg phi-rad theta-rad psi-rad] and tout is simulation time. NOTE: this is what I have so far - the output is still zero, looks like the simulation is not being stepped through
