| 中文摘要 | 在船载卫星天线指向控制应用中,为补偿MEMS角速度计零点温度漂移量,提高天线的姿态测量准确性和跟踪控制性能,提出了一种实时校正角速度计零点温度漂移的方法。该方法结合圆锥扫描原理,利用卫星天线接收信号功率的扫描数据来计算指向角误差。通过对指向角误差累计数据的判别,动态估计零点漂移趋势,然后对零点进行补偿。试验结果说明该方法可以有效补偿温度漂移。; In pointing control application of shipbome satellite antenna,in order to compensate the zero temperature drift of MEMS gyroscope and improve the precision of attitude measurement and tracking control performance of the antenna,the real time correction method for zero temperature drift of MEMS gyroscope is proposed.Combining with the principle of conical scanning,the error of pointing angle is calculated by using the scanning data of the signal power received from the antenna.Through the judgment of the accumulated error data of pointing angle,the trend of zero drift is dynamically estimated,then to do the compensation for zero point.The experimental results show that the method effectively compensates the temperature drift. |
