摘要
温度是影响陀螺仪漂移的重要因素。在试验的基础上,通过对某型硅微陀螺零漂数据进行小波滤波除噪,研究了既定温度范围内陀螺零漂的变化。基于最小二乘法原理,建立了陀螺仪的零漂补偿模型。通过补偿使陀螺的零漂稳定性由0.275 1°/s减小为0.011 4°/s,提高了零漂稳定性。从补偿的效果来看,多项式模型能够有效地补偿零漂,从而满足工程应用的需要。
Temperature is an important factor affecting the zero drift of gyro. On the base of experiment, by demonizing the data of one silicon micro-machined gyro with the wavelet filter technology, the zero drift of gyro at the over certain temperature is researched. Based on the principle of least square method, the model of compensation on zero drift is built. By compensation, the value of zero drift stability reduces from 0.2751°/s to 0.0114°/s. This enhances the zero drift stability. From the effect of compensation, polynomial model can compensate zero drift effectively and satisfy the need of engineering.
