Then in allusion to biased momentum wheel system, based on classical control system a pid controller was design about pitching channel. according to specialty of roll - yawing channel, this paper discuss long - time cycle movement and short - time cycle movement. when design the control method of long - time cycle movement, whiff thruster is used to assistant the control system. when design the control method of short - time cycle movemen, in order to sovle the problem of coundn ’ t abtain the angular velocity signal, nonminimum phase controller advanced by terasaki is used
然後針對偏置動量飛輪系統，基於經典控制理論設計俯仰通道的pid控制律，根據滾動?偏航通道耦合的特點，分別討論了由軌道角頻率和章動頻率引起的長周期運動和短周期運動。其中長周期運動控制律設計時，結合了噴氣推力控制來輔助偏置動量控制;短周期運動控制中，為了解決不能獲得角速度信號的問題，採用terasaki提出的非最小相位控制器進行控制。 -

Redo phase roll forward
重做階段（前滾） -
With norecovery omits the undo phase to preserve uncommitted transactions. omitting the undo phase allows for restoring other backups to roll the database further forward in time
數據庫開始新的恢復路徑后，將不能應用任何預先存在的且在恢復分叉點之後創建的日誌備份。 -
With recovery includes both the redo and undo phases and recovers the database ; additional backups cannot be restored. this is the default. if the roll forward set has not been rolled forward far enough to be consistent with the database, the undo phase cannot occur
