結線分割式冗長形レゾルバの非干渉制御による角度検出法

This study proposes angle detection technique to reduce angular errors due to the coupling between the two windings of a split-winding dual resolver. The proposed technique comprises two elements. First, the voltage frequencies of the two excited windings of the split-winding dual resolver differ from each other. Secondly, the sampled voltage of one of the output windings is processed to reduce the interference voltage from one other winding. The experimental results indicate that the proposed technique can reduce the angular errors substantially.
