PI regulation of the aeromechanical model of a Direct-Drive Wind Turbine

Although Direct-Drive Wind Turbines (DDWT) were previously studied, there is no consensus in the role played by the highly non-linear aerodynamic behaviour of the wind turbine rotor. In this work, some results are reported in terms of the aerodynamic derivatives.Further, a numerical example of the use of Proportional Integral (PI) control applied to the aeromechanical model of a DDWT is presented. The designed control accomplish a typical wind turbine control specification. It can be concluded that, for the linearized model, the PI control is enough to guarantee regulation.
