摘　　要：针对电子储纬器应用,研究了一种无刷直流电机转速平稳控制策略,基于无刷电机空间矢量控制模型分析了电流换相控制和齿槽效应导致转矩脉动的发生机理,提出了基于改进空间矢量脉宽调制与齿槽转矩脉动补偿的转速平稳控制方案,并在高速数字信号处理器软硬件平台上实现了无刷直流电机的转速实时稳定控制算法。500 W无刷电机试验台以及实际织造环境下的试验结果表明:所提出方案能够有效抑制无刷直流电机转速波动幅度,显著降低电子储纬器断纬事件发生几率,提高织造生产效率。A stable speed control strategy for brushless DC motor（BLDM） was investigated for the electronic weft feeders. The torque fluctuation mechanism of BLI）M was analyzed based on the space vector control model, which was mainly caused by the current commutation operation and the slot effect. Hence stable speed control scheme was carried out based on the improved space vector pulse width modulation （SVPWM）and the slot torque fluctuation compensation. And the real-time stable speed control algorithm was further developed with a hardware and software platform of high speed digital signal processor （DSP）. The experimental result obtained from 500 W BLDM test bench, as well as the field test of electronic weft feeder indicates that the proposed methodology can suppressed the speed fluctuation efficiently. Consequently, the terruption events caused by weft broken can be reduced and the weaving productivity can be improved significantly.
