一种模型与数据耦合驱动的弯曲回弹补偿方法
摘要：
本发明提供一种模型与数据耦合驱动的弯曲回弹补偿方法，步骤1：预设经验值Kc0＝0.2带入代数方程一次试压后得到第一组数据(h1,α1)，将第一组数据带入代数方程，经过计算测量得出另外三组数据(h2,α2)、(h3,α3)、(h4,α4)，将这四组数据拟合成一次函数α＝Kbh+b，求出Kb值；步骤2：将Kb值代入稳态模型Kc＝0.9/Kb，求出真实值为KcR，将KcR反带回代数方程公式由新公式再得出两组数据(h5,α5)、(h6,α6)，利用这两组数据对回弹后弯曲角α4进行精确回弹控制。
摘要（英）：

The invention provides a method for compensating for bending resilience of coupling driving of a model and data. The method comprises the following steps of 1, substituting a preset empirical value ofKc0=0.2 into an algebraic equation to obtain a first group of data (h1, alpha1) after one pressure testing, substituting the first group of data into the algebraic equation to obtain another three groups of data (h2, alpha2), (h3, alpha3) and (h4, alpha4) through calculation and measurement, and fitting the four groups of data into a primary function of alpha=Kbh+b to obtain the value of Kb; and2, substituting the value of Kb into a steady-state model of Kc=0.9/Kb to determine the real value as KcR, substituting the KcR back to the algebraic equation formula to obtain two groups of data (h5,alpha5) and (h6, alpha6), and carrying out accurate rebound control over the bending angle alpha4 after rebounding by using the two groups of data (h5, alpha5) and (h6, alpha6).
