针对由于陀螺抗过载能力差限制传统捷联惯性测量系统使用问题,以高速旋转弹药制导化应用为背景,提出了一种十二加速度计配置方案。在分析比较几种常见角速率解算算法基础上,通过优化组合得到了一种特别适用于高旋弹药而且不随时间积累的角速率解算算法,最后利用计算机仿真验证了该算法的有效性。仿真结果表明,该算法不随时间积累发散,在提高角速率解算精度的同时有效避免了角速率解算过程中符号误判和过零震荡现象。

In view of the limits of gyro's performance and with the background of application in guidance of high rotation ammunition, a scheme with 12 accelerometers was proposed. In this scheme, two kinds of angular velocity solution algorithm were obtained with the help of accelerometers' outputs which restrained errors growing with time. Finally, the deduction process of the novel method was discussed and validity of it was confirmed by simulation results. The simulation results show that the algorithm does not accumulate or transpire over time; to some extent, it also can effectively improve the precision of angular velocity solution. At the same time, the problem of symbol miscarriage of justice in the process of angular velocity solution was solved effectively.
