An optimal parity vector test method with good robustness is used to detect cycle slips, and then it can be restored.

这里采用鲁棒性好的最优奇偶向量方法检测周跳并进行修复。

The method for fault isolation is presented by separating this fixed direction from the directions in the parity space of the other factors by using the optimal transformation matrices.

通过选取最优转换矩阵，将这一方向与其它因素在一致空间中所在方向相分离，提出一种故障隔离的方法。
