Abstract :
This paper investigates globally asymptotical stability issues of two-dimensional linear time-invariant (LTI) switched systems with saddle points. Without resort to any general stability analyzing techniques or ideas based on any type of Lyapunov functions, this paper proposes a globally asymptotical stability (GAS) criterion for such kind of switched systems under arbitrary periodical/quasi-periodical switchings via the classical Lyapunov stability concept. A numerical example and its simulations illustrate the new stability result is correct and effective.
