Output-constrained invididual pitch control

This README will describe the code found in this repository entry and describe how this code and data was used towards the publication "Output-constrained individual pitch control methods using the multiblade coordinate transformation: Trading off actuation effort and blade fatigue load reduction for wind turbines". [Input the proper citation once a preprint is available.]

Data and code for WES publication: "Output-constrained individual pitch control methods using the multiblade coordinate transformation: Trading off actuation effort and blade fatigue load reduction for wind turbines"

Getting started

You can get started in two ways:

1. Define a case in generate_cases.py, run the case with Run_cIPC.m or multiple cases with Run_batch_cIPC.m, and then analyze with a script inspired by Plot_WES.m or Plot_NAWEA.m.
2. Download our results and put them in the Results/data folder. You can now analyze all the results using Plot_WES.m.

Folder structure

• IEA-15-240-RWT
  • Defines the IEA 15 MW reference turbine. Adjusted from GitHub, see IEA-15-240-RWT/README.md for the changes made.
• preplot-postplot (optional)
  • My plotting utilities to make nice plots with less boilerplate, available on GitHub.
• Results (optional)
  • data: Stores simulation data to be used by plotting scripts. If you want to recreate our results, store our datasets in this folder. This folder has folders that mirror the folders of InputFiles. Then for each folder, there are folders indicating what reference signal was used by the controllers (e.g. ref0 for a 0 Nm reference), then finally for each simulation there is an .outb file with OpenFAST outputs and a .csv files which also contrains logged signals from Simulink.
  • figures: Stores resulting figures.
  • InputFiles: Stores input files used by OpenFAST to run the different cases.
• src:
  • Helper: Contains helper functions.
  • Lib: Library with some static data (linearizations and optimal azimuth offsets).
  • Models: Constains the different Simulink models.
  • TempCache (optimal): Temporary cache folder.
  • generate_cases.py: Generate input files to run different cases (wind speed, turbulence intensity, etc...).
  • Plot_XYZ.m: Scripts to plot the results.
  • README.md: This README.
  • Run_batch_cIPC.m: Script to run many OpenFAST simulations with ℓ2 and ℓ∞ output-constrained IPC.
  • TurbSim_x64.exe: TurbSim executable to generate turbulent wind files when running generate_cases.py.

Software used

• Python 3.12.1 with the OpenFAST toolbox
• Matlab and Simulink R2022a with the preplot-postplot toolbox for plotting
• OpenFAST 3.5.0
• TurbSim v2.0
