The motor servodrivesystem was used to control antenna turning, adjust the antenna to point at satellite again and receive signal.
再用电机伺服驱动系统控制天线转动，调整其重新指向卫星接收信号。

To meet the demand of servodrivesystem, the vector control technique is chosen as the control strategy of permanent magnet synchronous servo system.
结合伺服传动控制系统的要求，确定永磁同步电机伺服系统的控制方案为矢量控制。
