摘　　要：研究采用转子磁场定向的矢量控制方法使无刷直流电动机定、转子磁势矢量始终保持正交,结合滞环调制电流控制和空间电压矢量调制,设计了无刷直流电动机滞环电流SVPWM控制方案。运行结果表明,此方案能有效地抑制无刷直流电动机低速时的转矩脉动,更好地改善系统的动态性能。Adopting rotor field-oriented vector control methods, through which make the stator and the rotor magnetmotive forces can be kept orthogonal all along during operation of the BLDCM, combining hysteresis current modulation＇s current control advantage and space voltage vector modulation＇s torque ripple attenuation advantage, then designing a sort of BLDCM hysteresis current SVPWM control method. The experiment results indicate that this method is more effective in the brushless direct current motor＇s low speed torque ripple attenuation, and its more effective in improving system dynamic performance.
