Abstract：In order to improve the convergence speed of the online parameter identification results of the permanent magnet synchronous motor and reduce the steady-state error, firstly, the voltage equation of the surface-mount permanent magnet synchronous motor (SPMSM) considering the voltage compensation of the nonlinear factor of the inverter is transformed to eliminate the influence of the error voltage. On this basis, this paper proposed a variable step size Adaline neural network algorithm to identify the parameters of surface-mount permanent magnet synchronous motor. The experimental results show that the proposed method can effectively reduce the steady-state error of stator resistance, inductance and rotor flux identification, and improve the convergence speed of the identification results.
