摘　　要：通过分析不对称单相感应电机(SPIM)在不同形态下的数学模型,解决了椭圆形磁场和电机不对称运行的问题。通过电压和电流混合模型磁链观测器计算转子磁链,并进一步计算转子磁链位置和转子转速。在三桥臂逆变器基础上,进行了基于转子磁场定向的不对称SPIM无速度传感器矢量控制仿真,验证了该控制系统的可行性与有效性。By analyzing the mathematical model of asymmetric single-phase induction motor(SPIM) in different forms, the problems of oval magnetic field and asymmetric operation of SPIM are solved. The rotor flux is calculated by a voltage-current hybrid model rotor flux observer, and the rotor flux position and rotor speed are further calculated. Based on the three-leg inverter, the simulation of speed sensorless vector control of SPIM with rotor-field orientation is carried out, the feasibility and effectiveness of the control system are verified.
