[Abstract]:For fiber optic gyroscope (fog) which is used in full temperature range, the change of input axis misalignment angle with temperature is one of the important indexes that affect the performance of fog inertial system. Especially in the application of large angular rate or high precision, the error of misalignment is even greater than that of zero offset drift error and scale factor error. Temperature compensation is an effective method to improve the temperature performance of fiber optic gyroscope (fog). This paper presents a fast modeling compensation method for full temperature misalignment of fiber optic gyroscope (fog) with continuous rotation. Based on the continuous rotation of the uniaxial speed turntable, the inflection point of the fiber optic gyroscope (fog) misalignment angle can be effectively identified in the full temperature range, and the accuracy of modeling and compensation can be improved. The experimental results show that the misalignment angle of the full temperature input axis of a fiber optic gyroscope is about 14 ", and the error angle of the full temperature input axis is less than 1" after compensation, and the precision is improved by more than one order of magnitude. In high-precision fog inertial system, this method can be used to guide the research and engineering realization of real-time temperature compensation of fog misalignment angle.
