Application of Multirate Sampling Approach in Pitch Control of Wind Generator Systems

摘要：

　　Pitch control is very important for variable-speed variable-pitch wind generator systems(VSVP-WGSs)working in high wind speed region.Dynamic inversion control is an emerging method applied in this situation.As the dynamic inversion method is very sensitive to parameters accuracy,a dynamic inversion control strategy based on multirate sampling is proposed in this paper.Multirate sampling method can be applied in the control of VSVP-WGSs in high wind speed region and provide good system performance even with parameter uncertainty.This approach simplifies the wind generator to two-mass model.This model is closer to the real system than the first-order dynamic model.Compared with traditional dynamic inversion controllers,the proposed method can increase system margin and guarantee the system with a better performance when parameters or external conditions change.These capabilities of the controller have been verified by analysis and simulation.
