The scalar lyapunov function approach and vector lyapunov function approach of stability for large - scale systems are analyzed . and it is pointed out that the restriction of these approaches are only suited for large - scale systems with week coupling among subsystems 对大系统稳定性的标量lyapunov函数法和向量lyapunov函数法作了分析，指出这些方法只适用于子系统间具有弱耦合的大系统的局限性。
