反双曲函数

还没有包含反双曲三角函数&反双曲余弦、反双曲正弦和反双曲正切。

The inverse hyperbolic trigonometric functions acosh , asinh , and atanh are not yet included .

证明了利用反双曲正弦函数变换能提高数据列的光滑程度，给出了改善的自回归预测方法，并且举例加以论证。

This paper proves that the smooth degree of a data row can be increased by transforming the counter-hyperbolic sine function .

提出了“利用反双曲正弦函数变换提高数据列光滑程度”的新结论，获得了递增时间序列改善的自回归预测新方法。

A new conclusion is put forward , in which the smooth degree of the data row can be enhanced by means of the arc-hyperbolic sine function transformation .

其次设计了一个具有良好的鲁棒性和快速性的滑模变结构控制律，采用了反双曲正切函数，避免了滑模变结构控制中的抖振问题。

Secondly , a sliding mode variable structure control law with good robustness and rapidity is designed . We use reverse hyperbolic tangent function to aviod the chattering problem in sliding mode variable variable structure control .
