摘要：
As a result the control accuracy is not high. As to the flux estimation，the principle of the generalized proportional integral observer is used to design a stator flux observer，based on which the flux prediction algorithm，strengthened with error correction，is further developed. Consequently，the prediction accuracy is enhanced. To expand the candidate voltage vector set，a dodecagonal voltage vector set，with the candidate ends uniformly located on the twelve vertexes，is proposed，by which not only do the candidate vectors be enriched，but also the harmonics are allowed to be suppressed further due to the dodecagonal merits. With the core algorithms presented above，a FCS-MPFC scheme is developed for the PMSG in wind energy system. As shown by the experimental results，the parameter robustness is greater and the torque accuracy is higher. © 2023 Science Press. All rights reserved.
