三轴角度传感器的轴间正交误差及增益偏差很难通过提高制造工艺得以消除,而这些误差及偏差极大地限制了角度传感器的精度。“三轴角度测量装置轴间正交误差及增益偏差修正算法”提出了一种可以同时修正测量轴轴间正交误差及轴间增益偏差的方法,实现了测量系到等增益正交系的变换。为此,构造并求解了关于参数最优估计的五元三次方程,并对该算法的收敛性及噪声对变换精度的影响进行了评估。 Triaxial angle sensor axis orthogonal error and gain deviation is difficult to eliminate by improving the manufacturing process, and these errors and deviations greatly limit the accuracy of the angle sensor. “A method for correcting the orthogonal error and the gain deviation between the axes of the three-axis angle measuring device ” proposes a method that can correct both the orthogonal error between axial axes and the gain deviation between axes, and realizes that the measurement system is orthogonal to the equal gain Department of transformation. For this reason, we construct and solve the quintic cubic equation about the optimal parameter estimation, and evaluate the convergence of the algorithm and the influence of noise on the transformation accuracy.
