	This Bladed-style DLL controller is used to implement a variable-speed generator-torque controller and PI collective blade pitch controller for the NREL Offshore 5MW baseline wind turbine. This routine was originally written in Fortran by J. Jonkman of NREL/NWTC for use in the IEA Annex XXIII OC3 studies.
