惯性组合稳定性优选稳健算法

从工程实际出发，对惯性组合稳定性优选问题提出了一种可行稳健的算法；将惯性组合一次标定参数提取为多维特征向量，通过计算特征向量方向余弦值方法来对比稳定性，通过实际惯性组合的标定数据进行了算例验证并分析了算法复杂度，算法简洁且计算耗时少，符合武器使用流程对解决惯性组合稳定性判读问题的可靠性、迅速性要求。

An Algorithm for Analyzing IMU Stability Performance

This paper proposed a stable algorithm for analyzing inertial measurement unit stability perform ance from the engineering reality, extracted the measurement data of inertial measurement unit to be a multidimensional feature vector, and then calculated the cosine between different multidimensional fea ture vector to contrasted the stability performance. At last, it verified the applicability by realistic measure ment data and analyzed the complexity of the algorithm. The algorithm is concise, which is in line with the weapons using processes and can solve the problem stability and rapidly.
