Stability of a Class of Nonlinear Large Scale Composite Systems
一类非线性组合大系统的稳定性

In this paper the stability foir a more general class of nonlinear large scale composite systems are considered. Based on Lemma 2 in this paper, two new stability criteria for this class of systems is given. Since the obtained stability criteria in this paper is only associated with the stability of the subsystems and the coupled terms among these subsystems, therefore, the difficulty to find Lyapunov functions of the nonlinear large scale composite system and its subsystems can be overcome for checking the stability of the large scale composite system by these two stability criteria.
