Version 2.7.0

Added Features:

• IPC saturation modes (IPC_SatMode)
• Pitch actuator faults: simulate constant blade pitch offsets. More is possible in future releases.
• Ability to initialize filters with specific values
• Support for latest OpenFAST version (v3.4.0)
• Add a tool for updating DISCONs from older ROSCO versions

Bug Fixes:

• Initialize NacIMU_FA_Acc and FA_Acc to 0. Initial conditions would result in offset of floating feedback pitch command
• Fix cases where debug outputs ***********
• Add nacelle heading (NacHeading) input to ROSCO
• Add method for closing dll in control interface on Windows
• Fix units in sim.py

Software Changes:

• Support for the latest numpy version (1.24)
• Re-named examples to represent the features they demonstrate
• Refactored ratelimit function to store it's own previous signal value
• Features that rely on collective blade pitch signal now use average of 3 current blade pitch values (useful in IPC cases)
• Clean up file readers/writers to sync with WEIS analogues
• Update features that rely on latest version of pyFAST
• Enable use of runFAST when python setup.py install is used.
• Add tune.py for specifically translating tuning yaml to controller objects and updating discon files
• When reading turbine model from openfast, only read necessary input module files

• Combined ROSCO and ROSCO_Toolbox (deprecating ROSCO_toolbox repo)
• Added robust control tuning
• Updated controller based on paper revisions, including Fl_Mode of 1 and 2 for translational and rotational floating feedback.
• Added flexibility to ROSCO tuning procedure (pass through floating feedback parameters, use multiple omega/zeta across wind speeds).

Minor Changes:

• Updated documentation
• Added support for Windows

Version 2.3.0

ROSCO Version 2.3.0

Some minor bug fixes and updates since version 2.2.0

Major updates

• Improved error handling, debug printing
• Input parsing
• CI testing for build

Minor Updates

• PR Template added
