AI总结:

本文研究了三维Filippov系统中边界平衡点的稳定性,通过分析四参数族分段线性混合系统的再注入机制,揭示了稳定性决定因素。

摘要:

对于三维分段光滑常微分方程系统,本文研究了属于切换面且是系统两边邻近部分中恰好一个平衡点的点的稳定性。当附近轨道反复在切换面的一侧进行常规运动,而在切换面上进行滑动运动时,稳定性变得难以刻画。本文证明在这种情况下稳定性由四参数族分段线性混合系统的一个全局再注入机制的行为决定,并对这一族进行了详细的数值研究。

英文摘要:

For three-dimensional piecewise-smooth systems of ordinary differential equations, this paper characterises the stability of points that belong to a switching surface and are equilibria of exactly one of the two neighbouring pieces of the system. Stability is challenging to characterise when nearby orbits repeatedly switch between regular motion on one side of the switching surface, and sliding motion on the switching surface, as defined via Filippov's convention. We prove that in this case stability is governed by the behaviour of a global reinjection mechanism of a four-parameter family of piecewise-linear hybrid systems, and perform a detailed numerical study of this family.
