Method of Cross Chords for Best - fit Polynomial Curves 最佳多项式曲线拟合的交叉弦线法
With a compensation of the bad accuracy lead screw, the accumulated errors compensation function of the lead screw pitch sorted and fit by the quadratic polynomial can reduce the affiliated disturbance of the error compensation, and conform the robot running at a uniform speed. 在丝杠误差补偿时,用二次多项式分组拟合丝杠螺距累积误差补偿函数,以减小修正量噪声引入,保证机器人工作速度的均匀性要求。
In this paper a method is proposed to fit data point with implicit polynomial 2D curves, to make the distance from the data points to the curve within the relatively smaller range. 本文提出了一种方法,用隐式多项式曲线拟合数据点,使数据点到多项式曲线的距离控制在相对较小的范围内。
And then through the vibration polynomial fitting residual method to analyze the degree of injury and identification of damage location, we fit the modal shape using polynomial fitting method by Matlab program and calculated the residuals. 进而通过振型多项式拟合残差方法来评价损伤程度及识别损伤位置,用Matlab编程对损伤前后各阶振型进行多项式曲线拟合,并且计算出拟合残差。
