Abstract

Automated methods for wind turbine controller tuning can be useful to obtain a rst estimation of the controller gains. Furthermore, these techniques can be employed within a multidisciplinary design procedure allowing for concurrent aeroservoelastic design. This report presents two methods to systematically tune the gains of the PI pitch controller of the Basic DTU Wind Energy Controller. The rst method is based on pole-placement technique and the second on fatigue loads reduction. Both methods require linear models of a wind turbine that are obtained with HAWCStab2. These techniques are solved with numerical optimization. The frequency placement method shows improvements compared to the state-of-the-art method but only when the model complexity is low. Tuning with load based method shows that different compromises between tower loads and rotor speed regulations can be achieved.
