摘　　要：直流变频空调PMSM压缩机频率范围宽,在30～100 Hz。拓宽频率从低频向下延伸至20 Hz,从高频扩展至120 Hz;低频范围下,电机振动幅度大,噪音严重,提出转矩补偿控制,但相位初始切入角难控制;高频下,弱磁控制与转矩控制的硬过渡明显,采用基因方法控制高低频,实验结果表明振动在55 dB下,同时提供了55 Hz和72 Hz的电流波形图。DC air conditioner compressor is a kind of PMSM, which runs in a wide range of frequency, from 30 Hz to 100 Hz. Operating frequency is extended to a low frequency of 0 Hz and to a high frequency of 120 Hz. Under low frequency expansion, however, the vibration and the noise affect the PMSM running in a low frequency. Thus, the torque control is proposed to function in 20 - 30 Hz. The initial phase angle is difficult to determine. The transition from torque control to field-weakening control lacks convergence. Hence, the immune control is presented to control wide frequency. The experiments show a low vibration of 55 dB and waveform of 72 Hz and 55 Hz.
