Implement control of 5MW\_MRSemi\_DLL\_WSt\_WavesIrr in Simulink

[okir385-cmd]

I am a beginner in Openfast and I want to use Openloop's Simulink file to control Openfast. I intend to implement control of this model in Simulink. However, the inputs for the official functional model are designed for a single wind turbine. I would like to figure out how to set up input signals for this dual-turbine model. Is it feasible to drag two FAST Nonlinear Wind Turbine blocks into the model for invocation?

Dear @okir385-cmd,

Can you clarify your use case? Are you trying to model a multi-rotor system on a single floating platform with distinct controllers for each wind turbine implemented in Simulink?

Best regards,

Yes, I aim to simulate a multi-rotor system mounted on a single floating platform, where each wind turbine is equipped with an independent controller to be implemented in Simulink. Additionally, I would like to know whether the 5MW_MRSemi_DLL_WSt_WavesIrr model in OpenFAST v5.0.0 supports such control architecture.

Dear @okir385-cmd,

At this time, the Simulink interface to OpenFAST has not yet been made compatible to work with the new multi-rotor functionality. Placing two OpenFAST nonlinear wind turbine blocks into the Simulink model is not the solution because the multi-rotor functionality of OpenFAST involves coupling between the rotors solved within the same executable. The other control options available in ServoDyn--including the simple built-in models and DISCON DLL controllers--do support the multi-rotor functionality.

Best regards,
