| 摘 要： | 本文针对旋转弹用弹旋基准问题，提出八加计惯性测量系统方案，并进行了加速度计静态标定实验，给出了静态标定算法及模型系数标定结果。在此基础上，设计了系统动态标定实验及误差补偿方案，在实验室自研高速转台上标出了转台加速过程的完整的动态误差补偿模型，实施了惯性测量系统的实验弹模拟实验。经标定补偿后的误差模型，解算滚转角在9S内最大累积误差为-4．071°。实验结果表明动态误差补偿模型能有效提高滚转角的解算精度，具有一定实际应用价值。

| Abstract: | In this paper, the static calibration of accelerometer is designed based on eight-accelerometer＇ SINS to solve the high-speed circumrotation projectile benchmark problem, then the static calibration algorithm and model modulus calibration result are proposed. On the basis of them, the system dynamic calibration experiment and error compensation scheme are designed. The integrate dynamic error compensation model in turn-flat speedup processing is calibrated in self-manufacture turn-flat, and implemented through projectile simulation experiment for SINS. Through calibration and compensation of the error-model, the accumulative error of roller-angle is --4.071° in 9 second. The result shows that the dynamic error compensation model is effective for roller-angle precision. And this method has some actual application value. |
