摘　　要：在矢量控制系统中,参数的准确性对电机的控制效果有着重要的影响。对传统的离线参数辨识方法进行改进,加入SVPWM技术、离散傅里叶变换,测得准确的定、转子电阻,定、转子漏感及互感。仿真结果表明该方法是有效的,且有较高的辨识精度。In vector control system,the accuracy of parameters has an im porta nt influence on the control effect of motor.To improve the traditional off-line parameter identification methods,SVPWM technology mnd discrete Fourier transform are applied which can accurate measure the stator and rotor resista nee,stator and rotor leakage inductanee and mutual inductance.Simulation results show that this method is effective ond has high identification accuracy.
