摘　　要：异步电机V/F控制在低速运行的情况下会由于死区效应而产生扭矩的脉动,严重影响到电机的正常运行。使用电压矢量定向的方法对电流进行解耦,可以为判断电流换向的时机提供依据。与传统的直接判断电流方向的方法相比,通过电压矢量定向的方法能够更加准确地判断出电流的方向,在相同的情况下,电压矢量定向的死区补偿方法能够使电流波形更加圆滑,输出更大的转矩。Due to the effect of the （lead zone, V/F control of induction moto operation will couse torque ripple and seriously affect the normal operation of the method of voltage vector orientation,the current decoupling can provide the basis for the current commutation. Compared with the traditional method of detecting the method of voltage vector orientation may more correctly for judging the direction of case the current waveform will be more smooth and the torque will be greater by compensation method of voltage vector oriented. r in the motor. judging current current. - speed By using the the timing of directly, the using the
