Supposing that the reference trajectory is generated by a stable system, the bounded solution of non hyperbolic internal dynamics is existed by using center manifold theory.
假设期望轨迹由某一稳定外部系统产生，利用中心流形的理论，证明了系统内部动态有界解是存在的。

By, proposes one kind of new hyperbolic measure, and has proven this measure is one kind of measure on the hyperbolic branch manifold.
