混杂系统的瞬时稳定性:多广义李雅普诺夫函数方法

Finite-Time Stability of Hybrid Systems: A Multiple Generalized Lyapunov Functions Approach

Kunal Garg, Dimitra Panagou

摘要:

研究了一类混杂系统的有限时间稳定性。我们提出的充分条件,在多个广义李雅普诺夫函数的起源的混杂系统是有限时间稳定的。更具体地说,我们表明,即使广义李雅普诺夫函数的值连续开关之间的增加,有限时间的稳定性可以得到保证,如果有限时间收敛模式是活跃的足够长。在早期的工作中,李雅普诺夫函数需要减少在连续流和非增加的离散跳跃,我们允许广义李雅普诺夫函数增加\emph{both}在连续流和离散跳跃。因此,与相关文献相比,推导的稳定性结果保守性较低。数值算例验证了所提方法的有效性。

英文摘要:

This paper studies finite-time stability of a class of hybrid systems. We present sufficient conditions in terms of multiple generalized Lyapunov functions for the origin of the hybrid system to be finite-time stable. More specifically, we show that even if the value of the generalized Lyapunov functions increase between consecutive switches, finite-time stability can be guaranteed if the finite-time convergent mode is active long enough. In contrast to earlier work where the Lyapunov functions are required to be decreasing during the continuous flows and non-increasing at the discrete jumps, we allow the generalized Lyapunov functions to increase \emph{both} during the continuous flows and the discrete jumps. As thus, the derived stability results are less conservative compared to the related literature. Numerical example demonstrates the efficacy of the proposed methods.
