| 摘 要： | 复合控制是提高光电跟踪系统跟踪精度的一种有效方法,它较好地解决了精度和稳定性之间的矛盾;而等效复合控制是复合控制的另一种实现。为了实现等效复合控制,采用加速度计直接测得加速度信息再通过积分得到的速度作为前馈控制信号。实验对比结果表明,加速度计可以作为等效复合控制的传感器,在实际应用中实现伺服跟踪系统精度的提高,加入等效复合控制的光电跟踪伺服系统的跟踪精度提高至原来的6.67倍。 |

| Abstract: | Compound control is an effective method for improving the tracking precision of opto-electronic tracking system,which can perfectly resolve the contradiction between accuracy and stability.Equivalent compound control is another realization of compound control.To implement equivalent compound control,the speed,obtained by integrating the acceleration directly measured by an accelerometer,was taken as the feedforward control signal.The experimental results show that the accelerometer is a good sensor for equivalent compound control to improve the precision of the opto-electronics tracking system.The tracking precision of the system with equivalent compound control can be improved by 6.67 times. |
| Keywords: | opto-electronic tracking system equivalent compound control accelerometer integral tracking precision |
