Advanced System Identification Techniques for Wind Turbine Structures

The new approach to modal parameter identification, presented in this paper, uses an asymptotically stable observer to form a discrete state-space model for a wind turbine structure. The identification is performed using input-output time-series. A special software package developed in this research has been tested using the data generated by the ADAMS model of the Micon 65/13 wind turbinestructure. Numerical and graphical presentation of some of the results, generated by the programs developed, illustrates the range of their applicability.
