非线性物理：混沌物理 控制方法的优点： 1.No model for the dynamics is required 2.The computations required at each iterate are minimal 3.The required changes in the parameter can be quite small 4.Different periodic orbits can be stabilized for the same system in the same parameter range 5.Control can be achieved even with imprecise measurements of the eigenvalues and eigenvectors 6.This method is not restricted to periodically driven mechanical systems,but extends to any system whose dynamics can be characterized by a nonlinear map. 非线性物理：混沌物理 控制方法的优点： 1.
