摘要
随机脉宽调制技术可以使逆变器输出电压的谐波成分均匀地分布在一个较宽的频率范围内,达到抑制噪声和机械振动的目的.把随机脉宽调制技术引入感应电机矢量控制系统中,保证了调速系统的高性能,同时也降低了电机的有色噪声和机械振动.
Random pulse width modulation technique can be used to distribute voltage harmonics over a wide frequency range and to realize the reduction of acoustic noise and vibration. This paper proposes a classic vector control system of induction motor operating with the random pulse width modulation. It shows that the good dynamic response inherited ftom the vector control can be maintained, meanwhile the subjective acoustic noise and vibration can be lowered.
