So it seems entirely possible to generate jsbsim config files from simulink subsystems. Most of the components of a jsbsim fcs already exist in simulink (gains, summers, pids, lookup tables etc.) Custom masked subsystem blocks could be designed for actuators and the fcs_function components. That would pretty useful if you could "build" a fcs_function as a block component/subsystem in simulink and then have it auto-generate the corresponding xml.
