摘要
本文提出了在三轴惯性综合测台上采用最优试验设计辨识捷联组合陀螺动态误差模型,只用四个位置就可以完成捷联组合陀螺21项动态误差模型参数的辨识.这种方法不仅试验时间短,而且模型估计精度,有利于全部测试自动化,在惯性测试理论应用上向前迈进了一步.仿真结果表明该方法正确实用.
An optional experiment design is proposed to identify dynamic error models of the gyros in strapdown inertial unit on the three-axes-turntable. Twenty-one parameters of the gyros'dynamic error models can be identified by only using four positions. The identification can be completed automatically in short time with high accuracy for estimating the models. It is shown that a great progress in application of inertial measurement theory has been made, and the results from simulation show mat the method is correct and practical.
