Abstract

Instead of avoiding the 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 the harmonic peaks and hence the acoustic noise. The key is to employ the Chua's circuit for generation of the desired chaotic sequence. By using a practical induction motor, both computer simulation and experimental results verify that the chaotic PWM takes definite advantages over the conventional PWM and random PWM, namely the harmonic peak suppression and simple hardware implementation.
