N2 - Permanent magnet synchronous motor can achieve static current decoupling based on field-oriented control (FOC), but the dynamic coupling relationship still exists. To achieve complete decoupling, some scholars proposed complex vector decoupling which includes a virtual axis zero point that varies with velocity. By drawing the zero-pole and bode diagram of the system, it can be found that the decoupling is not sufficient when the controller parameters are not set according to zero-pole cancellation. To solve this problem, A decoupling strategy with high integral coefficient robustness is proposed, which enables the current to be completely decoupled over a wide range of PI parameter settings. Finally, the feasibility and effectiveness of proposed method were verified by simulations.
