The correct definition and selection of voltage spacial vectors affect performance in two-phase conduction brushless DC motor( BLDCM) direct torque control( DTC) system directly. The definition method of voltage spacial vectors( including positive vector,negative vector and zero vector) suitable for two-phase conduction brushless DC motor was proposed. For the continuity of the inductor current and freewheeling diode,all-off voltage spacial vector is not a zero voltage spacial vector but the negative voltag...

0引言无刷直流电机(brushless DC motor,BLDCM)因其结构简单、价格低廉、调速性能良好等特点,在众多领域得到了广泛应用[1]。电机控制的本质是控制其转矩,无刷直流电机传统控制方法采用方波电流驱动,通过对导通两相电流的控制间接控制电机转矩,而直接转矩控制方法(direct torqu
