In this digest, a complex vector based uncertainty and disturbance estimator (CVUDE) current controller for permanent magnet synchronous machine (PMSM) is proposed. A theoretical analysis demonstrates the superiority of the proposed method, which enables the transfer function of the motor drives in complex vector format is uniquely determined without varying with the rotation speed. Meanwhile, the CVUDE can effectively mitigate unknown dynamics caused by the parameter mismatch and the extern disturbance caused by the non-linearity of the power inverter. Experimental results explicitly demonstrate that the CVUDE control method maintains excellent performance compared with the traditional PI algorithm, especially in the aspects of eliminating impacts of parameters mismatching and mitigating the current harmonics caused by non-linearity of the power inverter.
