摘要
首先给出了非线性自治系统离散线性化的理论基础;然后给出了二维自治系统在平衡点处散射的一个等价刻画,利用此等价刻画证明了所有的鞍点都是散射点;最后利用线性反馈的方法对二维自治系统进行了散射控制,并通过计算机仿真验证了此控制方法的有效性.
In this paper, a theory about the linear discretization of nonlinear autonomous systems is first given. Then an equivalent characterization of the scattering at the equilibrium point of a two-dimensional autonomous system is obtained. Based on this equivalent characterization, the authors prove that all saddle points are scattering points. Finally, the method of linear feedback is used to control the scattering points of two-dimensional autonomous systems. Computer simulation shows that this method is effective.
