摘　　要：针对微机电系统(MEMS)陀螺仪误差标定模型中输入和输出观测数据均含有噪声的情况,引入总体最小二乘这种能够顾及系数矩阵和观测值矩阵同时含有噪声的方法。分析基于DSP的MEMS捷联惯导系统中MEMS陀螺仪输出数学模型,以MEMS陀螺仪的速率标定为例建立基于总体最小二乘的误差标定模型,实验证明该方法具有良好的可靠性。Response to the situation that both input and output observational data contain noise in the er-ror calibration model of micro-electro-mechanical systems （MEMS） gyroscope, introduce the total least-squares method that can take into account the coefficient matrix and the observation matrix containing noise in both. Analysis the output mathematical model of the MEMS gyroscope in MEMS SINS based on DSP technology, to establish the error calibration model based on the total least-squares method taking velocity calibration of MEMS gyroscope for example, and experimental results show that the method good reliability. the has
