Abstract
By analyzing the d-q axis mathematical model of the permanent magnet synchronous motor (PMSM),a closed-loop identification method of quadrature-direct axis inductance,stator resistance and the rotor magnetic flux linkage is proposed for alternating current servo control an system. The influences of the motor model error caused by non-sinusoidal flux,the switch dead zone of inverter and the rotor position feedback delay caused by encoder on the parameter identification accuracy are analyzed. The compensation methods are introduced. The analytical and the experimental results show that,after being compensated,the identified inductance-current curves are consistent with the finite element analysis results. The identified resistance and flux are close to the measured values. These results confirm the validity of the method. The identified parameters are the equivalent parameters of the operating motor,so they can provide basis for design and modification of the controller and PMSM.关键词
