28379d快速电流环程序里面的比较值计算

if     (v.VecSector==1 || v.VecSector==4)                                   \
      {     v.Ta= v.tmp2;               \
        v.Tb= v.tmp1-v.tmp3;             \
        v.Tc=-v.tmp2;              \
      }                      \
                       \
    else if(v.VecSector==2 || v.VecSector==5)                                   \
      {     v.Ta= v.tmp3+v.tmp2;             \
        v.Tb= v.tmp1;               \
        v.Tc=-v.tmp1;              \
      }                      \
                       \
    else                                                                        \
      {     v.Ta= v.tmp3;               \
        v.Tb=-v.tmp3;               \
        v.Tc=-(v.tmp1+v.tmp2);            \
      }  

28379d快速电流环程序里面的比较值计算怎么也没搞懂 结果正确但是和其他的版本都不一样  那个大神可以指点一下
