This source file contains example PitchCntrl(), UserHSSBr(), ! UserVSCont(), and UserYawCont() routines that are used to interface ! FAST with a master controller implemented as a dynamic-link-library ! (DLL) in the style of Garrad Hassan s Bladed wind turbine software ! package. All four routines call routine BladedDLLInterface(), which ! contains a call to the Bladed-style DLL that evaluates as DISCON(). ! Routine BladedDLLInterface() USEs a MODULE named ! BladedDLLParameters(), which stores values of PARAMETER constants ! used in the interface.
