Claim 2:
3. The method according to claim 2, wherein Step (2) comprises:
ΔVXY(k)=VXY*(k)−VXY(k) when there is no switching of the three-phase switching control signals between the sampling points k and k−1, that is, when SA(k)=SA(k−1), SB(k)=SB(k−1), and SC(k)=SC(k−1) are satisfied; and not calculating ΔVXY(k), and regarding ΔVXY(k) at the current time as zero when one of SA(k)=SA(k−1), SB(k)=SB(k−1), and SC(k)=SC(k−1) is not satisfied, where ΔVXY(k) represents the deviation between the expected value of the phase-to-phase voltage between the X-phase and the Y-phase and the actual value of the phase-to-phase voltage.
