| 摘 要： | Instead of avoiding occurrence of chaos in motor drives,chaos is positively utilized in this paper.A new chaotic pulse width modulation (PWM) scheme is proposed and implemented for AC motors,which functions to significantly suppress harmonic peaks and hence acoustic noise.The key is to employ the Chua's circuit for generating a desired chaotic sequence.By using a practical induction motor,computer simulation and experimental results verify that the chaotic PWM has advantages of harmonic peak suppression and simple hardware implementation over the conventional PWM and random PWM.
