| 摘 要： | 开展了陀螺加速度计在三轴转台上的测试试验,由于三轴转台给陀螺加速度计提供的输入加速度引入设备误差,需采用总体最小二乘法对试验数据进行辨识。将最小二乘法应用于辨识陀螺加速度计在三轴台上的测试试验,主要是消除了测试设备的误差对陀螺加速度计精度的影响,与最小二乘法辨识结果进行比较,总体二乘法的辨识结果要优于最小二乘法,提高了陀螺加速度计的辨识精度。 |
| 关 键 词： | 陀螺加速度计 三轴转台 模型系数 总体最小二乘 |

| Abstract: | The testing of PIGA on the three-axes turntable is developed. Because the input acceleration provided by the three-axes turntable has facility error,the total least squares must be used to identify the testing data. The purpose of applying the least squares method to the identification of PIGA on the three-axes turntable is to eliminate the influence of the testing equipment error on instrument precision. Compared with the least squares method, this method can enhance identification precision of the testing PIGA. |
| Keywords: | pendulous integrating gyro accelerometer(PIGA) three-axes turntable model coefficient total least squares |
