【摘要】：在全溫范圍內應用的光纖陀螺,標度因數誤差是其主要的誤差之一。特別是在大角速率或者高精度應用時,光纖陀螺的標度因數誤差甚至超過零偏漂移誤差。在實際使用中,需對陀螺標度因數在全溫范圍內進行建模和補償。對光纖陀螺標度因數誤差機理進行詳細分析后,提出了一種連續(xù)旋轉的光纖陀螺全溫標度因數快速建模補償方法�；趩屋S速率轉臺的連續(xù)旋轉,可以自動快速完成標度因數全溫建模且工程實現簡單易行。更重要的是該方法可以有效識別標度因數在全溫范圍內的變化拐點,提高建模和補償的精度。對比試驗結果表明,采用此方法后能精確測得某型光纖陀螺全溫工作的標度因數真實拐點為48℃,全溫標度因數補償精度優(yōu)于15′10~(-6),較按照GJB2426-2004進行的多點測試后補償提高10%左右。
[Abstract]:Scale factor error is one of the main errors of fiber optic gyroscope (fog) which is used in full temperature range. Especially in the application of large angular rate or high precision, the scale factor error of fiber optic gyroscope is even greater than zero offset drift error. In practical use, the scale factor of gyroscope should be modeled and compensated in full temperature range. After a detailed analysis of the error mechanism of the scale factor of fiber optic gyroscope, a fast modeling and compensation method for the total temperature scaling factor of fiber optic gyroscope with continuous rotation is proposed. Based on the continuous rotation of the uniaxial speed turntable, the scale factor full temperature modeling can be completed automatically and quickly, and the engineering implementation is simple and easy. More importantly, the method can effectively identify the inflection point of scale factor in the whole temperature range, and improve the accuracy of modeling and compensation. The experimental results show that the real inflection point of the scale factor of a fiber optic gyroscope at full temperature can be accurately measured by using this method, and the true inflection point of the scale factor is 48 鈩，
