About qlpv form of wind trubine

[newsagas]

Can the wind turbine model be written in the form of the qlpv model, that is, the ABqL_WT_beta.m file? Is it only applicable to the MPC control algorithm? I have no idea how to start building a wind turbine in lpv form. Could you provide some guidance? Thanks.

Can the wind turbine model be written in the form of the qlpv model, that is, the ABqL_WT_beta.m file?
The ABqL_WT_beta.m file will indeed provide the system (A) and input (B) matrices for a q-LPV model. As you will see in the code, the states are slip angle Theta_s [rad], rotor speed omega_r [rad/s], generator speed (measured on the rotor side) omega_gr [rad/s], and generator torque T_g [Nm]. The inputs are the effective wind speed V [m/s], the blade pitch beta [rad] and the generator torque T_g [Nm]. The scheduling parameter rho consists of the measurement values of wind speed V, pitch angle beta and rotor speed w_r.
Is it only applicable to the MPC control algorithm? No, in fact we only slightly extended a wind turbine model that was proposed in this book: F. D. Bianchi, H. De Battista, and R. J. Mantz, 'Wind turbine control systems: principles, modelling and gain scheduling design'. SpringerScience & Business Media, 2006.
I hope this answers your question. Please feel free to reach out to me at my DLR address, if you have further questions or problems running my code: antje.dittmer@dlr.de
