A new brushless DC motor DTC scheme was studied to solve those problems associated with direct torque controlof brushless DC motor,such as difficulty to control flux and complexity to estimate torque.The flux hysteresis controller was ignored in the constant torque region and an improved method was proposed to make the estimation of torque easier.The proper stator voltage space vector was selected based on the output of the torque hysteresis controller and the sector which the current rotor flux locates in.

Theoretical analysis and simulation shows that the direction driving motor accelerates first, and then decelerates to compensate for the eccentricity when the satellite is deviated from laser center with a certain distance, and reacquires the tracking satellite. The needed time from reacquisition to tracking is affected by motor acceleration, telescope′s detecting precision, and detector′s response and treatment time, and the effect of detector precision on the reacquisition and re-tracking time is greater, as a result, the detector response and treatment time is decreased to the least.

理论分析与仿真结果表明，当卫星偏离光斑中心一定距离时，指向驱动电机先加速后减速，补偿这个偏心，重新捕获跟踪卫星；重新捕获到跟踪所需时间受电机加速度和望远镜探测精度以及探测器响应处理时间影响，其中探测器精度对重新捕获到跟踪所需时间影响较大，探测器响应处理时间要减小到最小；为了使从捕获到跟踪过程中卫星始终在扫描光斑范围内，经纬仪驱动电机的最小角加速度为25.5°/s2。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
