> Hello all, As part of my PhD work, I’m applying the Universal Differential Equations (UDE) approach seen in [Automatically Discover Missing Physics by Embedding Machine Learning into Differential Equations · Overview of Julia's SciML](https://docs.sciml.ai/Overview/stable/showcase/missing_physics/#Symbolic-regression-via-sparse-regression-(SINDy-based)) to estimate the controller of a wind turbine. I’m using a simple aerodynamic model with three states (rotor speed wr, generator torque Tg and blade pitch β) and one exogenous input (the wind speed vr). I lack knowledge of the controllers responsible for computing th…
