Motorware的FOC lab中的svgen

实例中FOC中svgen程序如下：
 Va_tmp = -(pVab->value[0]>>1);
 Vb_tmp = _IQmpy(SVGEN_SQRT3_OVER_2,pVab->value[1]);
 Va = pVab->value[0];  //alpha
 Vb = Va_tmp + Vb_tmp; //-0.5*alpha + sqrt(3)/2 * beta;
 Vc = Va_tmp - Vb_tmp; //-0.5*alpha - sqrt(3)/2 * beta;
 if (Va > Vb)
  {
    Vmax = Va;
    Vmin = Vb;
  }
  else
  {
    Vmax = Vb;
    Vmin = Va;
  }

  if (Vc > Vmax)
  {
   Vmax = Vc;
  }
  else if (Vc < Vmin)
  {
    Vmin = Vc;
  }

  Vcom = _IQmpy(Vmax+Vmin, _IQ(0.5));

  // Subtract common-mode term to achieve SV modulation
  pT->value[0] = (Va - Vcom);
  pT->value[1] = (Vb - Vcom);
  pT->value[2] = (Vc - Vcom);

请问，有这个sv的说明么？我把常规的sv算法替换进去，电机不会转。我用的常规sv算法，和附件中的原理相同。只是替换时候我有做修改。请问怎么将常规的sv用到FOC中？谢谢
