N2 - To reduce costs and improve performance, sensorless control is widely adopted for permanent magnet synchronous motor (PMSM) drives. In the low speed range, the high-frequency injection method can be used, but the harsh noise limits its application. In this paper, a random high-frequency square-wave voltage injection sensorless control method based on chaotic mapping is used for reduce the additional noise. Four kinds of square-wave signals with different frequencies and amplitudes are selected in this control strategy, and the chaotic mapping method is used to generate a random number sequence. According to the value of the random number sequence, the type of injected square-wave is selected. Then the signal processing process of random high-frequency square-wave injection is deduced. Finally, the experimental verification is carried out on the platform of PMSM drive, and the effectiveness of the scheme is proved by the analysis of the motor phase current power spectral density (PSD).
