- •
An improved reduced-order transfer-function model of an electric pitch drive system for a wind turbine is proposed.
- •
Frequency characteristics analysis, simulation, and experimental test are carried out to validate the improved model.
- •
The improved model is superior to a first-order model for the performance analysis of a wind turbine pitch angle controller.
- •
The improved model can meet the requirements of large-scale simulations on the loading characteristics of a wind turbine.
