摘要
针对测量船伺服系统存在随机误差的情况,为提高角误差的精度,基于著名的Singer模型建立了航天测量船伺服系统卡尔曼滤波算法,并通过计算机进行了实际测量数据的仿真实验。从实验仿真结果分析可看出,采用提出的算法,能够较大程度的减小角误差电压含有的随机误差,验证了本方法的有效性,达到了提高测量船测控精度的目的。
Analyzing the controling structure of Servo System of Space Survey Vessel, the Kalman filter using in Servo System of Space Survey Vessel is put forward based on the famous Singer Model. The simulation on the real measured data is carried on. The result of simulation shows that this method can highly decrease random error in the voltage of angle error and the accuracy of Measuring Angle System can be improved more.
