| 摘 要： | 研究了一种利用PWM逆变器载波频率成分信号进行内置式永磁同步电机(IPMSM)转子位置估算的方法。逆变器应用三相三角载波SPWM调制方式,通过检测载波频率成分电流(CFCC)的包络线估算出电机的转子位置。分析了电机转速、直流母线电压、逆变器载波频率等因素对转子位置估算误差的影响。实验结果表明,该方法能够实现对电机转子位置的准确估算,所构建的IPMSM无位置传感器矢量控制系统具有良好的动、静态性能。在此基础上对影响转子位置估算误差的相关因素进行了仿真和实验验证,结果证明了理论分析的正确性。

| Abstract: | A rotor position estimation method for interior permanent magnet synchronous motor(IPMSM) is researched utilizing carrier frequency component signal of PWM inverter.Three-phase triangular carrier SPWM modulation is adopted in the inverter.The rotor position is estimated by detecting envelope curves of the carrier frequency component currents(CFCC);the effects of the rotor position estimated error,such as the motor's speed,DC bus voltage and the carrier frequency of inverter are analyzed.The experimental res... |
