N2 - By using the vector control for permanent magnet synchronous motor (PMSM), the current static decoupling is realized, however, the dynamic coupling still exists. Some conventional methods achieve dynamic decoupling to some extent but these methods depend on specific motor parameters. To solve this problem, this paper proposes a decoupling control method applied to PMSM drives via vector control and uncertainty and disturbance estimator (UDE). The coupling terms and parameter uncertainties are modeled as disturbance and an UDE is used to observe the disturbances. The observed disturbances are used to compensate for the output of the current-loop PI controller. Additionally, this paper demonstrates the decoupling ability of the proposed method by deriving its equivalent form. The simulation results indicate that the proposed controller has a good decoupling effect and a strong robustness to parameters variation.
